View Full Version : LS3/5a


February 15th 08, 02:05 AM
Now that we are a snot-free forum, I'd like to throw out the first
audio discussion. I've been listening to these Stirling Broadcast
LS3/5as for a few weeks now, and I'm digging them. I'm amazed at how
smooth and full they sound, despite being about the size of a shoebox
(kids' shoes, even). Sure, I'm powering them with a conrad-johnson
ET250s amp and both a Nagra PL-L and McIntosh C2300 preamps. But man,
am I surprised by the sound. I've heard LS3/5as in the past, and they
never sounded anything like this.

Any other LS3/5a fans here? Critics?

I think they might be just the thing for vinyl, but not for CD.

I should resent that, but I don't.

**Over-rated and under-performing. There are MUCH better (more accurate)
products available. My own favourite is the late, lamented NEAR 10M-II. A
stunning performer, easily capable of embarrassing the more expensive NEAR
products and pretty much anything remotely close to it's original retail
price. I still use mine. I've never owned a pair of speakers for as long as
I've owned my NEARs.

**They may have been 16 Ohms once, but I suspect they're 8 Ohms now. In any
case, a 16 Ohm load is hardly a problem for virtually any amplifier. Just
halve the rated power into 8 Ohms.

These are 11-ohm. I've run them with the Clayton Audio Stereo 40,
which is 50 wpc of pure Class A, and the conrad-johnson ET250s, which
is 250 wpc. The Stirlings definitely like the extra power.

I like the NEARs as well, always have. Great match with Exposure
electronics. I remember choosing my Spendor S20s over LS3/5as back in
the early '90s. Back then, LS3/5as were $750 a pair. These Stirlings
are $1850 a pair. Still, I think this version is the best LS3/5as
I've heard.

I reviewed the Stirlng LS3/5a a year ago. You can
find the reprint of that review starting at

On balance, I slightly preferred the similarly sized

Been there, done that.

I first heard of LS3/5a speakers back in the late 60s. There were a spate of
minispeaker clones, some made by other British manufacturers. I heard a lot
of the clones.

Eventually, I heard a pair of the origionals. Bright, smooth, well-balanced
given that they had no real bass. No directional control because of the tiny
size, so they need a fairly dead room or be listened to very close. Probably
the origional prototype of the near-field monitor genre of speakers.

Very impressive for the day (long ago) and the size (very tiny). However,
that was then and this is now. Most of the time, people have the space it
takes to use a larger speaker. If you can, then do it and reap the benefits
of having some decent bass.

The loudspeaker state of the art has advanced considerably since the LS3/5a
was representative of the SOTA.

Probably equalled or surpassed by the NHT Super zero and many other modern
mini-monitors.

My recollection is that they have been made in several different impdeances
including 16 and 11 ohms.

>If so, how do ordinary amps hold up?

High impedance loads are easier to drive than low impedance loads because
they draw less current. Of course it takes more voltage to deliver a given
amount of power to them. The speaker is relatively inefficient for a number
of reasons, including the fact that it uses a passive crossover that
attenuates the midrange in order to pump up the bass.

More to the point - how do the speakers hold up if you try to play them
loud. The answer is not that well. We've learned a ton about building small
drivers with improved dynamic range in the past 50 or so years.

Actually, LS3/5a speakers can do a pretty good job of reproducing the
objectionable noise and distortion that is an inherent part of the LP
format. You'd have to be pretty deaf to miss it.

I heard the LS3/5a speakers back in the very late 70s or maybe 1980,
back when around the L.A. area there were several high-end
establishments that ran out of people's homes by appointment. Other
than the Quads, they were probably the first high-end speakers that I
heard. I was amazed at the clarity and imaging, but of course, there
was no real bass. I remember that this person had some slightly
larger Mordaunt Short speakers that I liked better. I almost bought a
pair of those, but ended up getting the DCM Timewindows instead as
part of my first non-mass market system (with the NAD 3020 and a
little Micro-Seiki TT.)

I'd have to agree. I really like the entire line.

Strangely enough, I just had a pair of vintage Celestion SL600s in for
a few days. I really, really enjoyed the SL600s at first, but after a
few days they started to sound a bit cloudy. When I put the Stirlings
back in, it was like a breath of fresh air. Less bass, but more
detail.

That's funny...I almost bought a pair of DCM Timewindows, but would up
purchasing a pair of Snell Type Js instead. This was around 1982. I
thought the Snells were every bit as good as the DCMs, but a couple of
hundred dollars less.

Well, Stirling is calling these the V2s since they're using new
drivers. Then again, they're trying to come as close to the very
first LS3/5as as possible.

Really? Let's see how that might go on Valentine's day...

"Why hello there, you beautiful speakers. Love your tweeters!"

"I just love a big shiny record. Want to come over and heat up

I have to admit I hadn't thought of that angle on matching speakers with
media. Nice job, Morein.

Have you tried them in nearfield listening? I'm finding that is their

I'm using them for both CDs and LPs with equal success. Remember,
these are modern version (V2) of the classic LS3/5a, with different
drivers.

I won't have them in 6 months...they'll go back to the distributor.
I've had them for a month already. Early next week I'll be getting a
pair of Devore Gibbon 9s in for review, and I'll be able to hold onto
those for a few months. I spent almost a year with the Gibbon Super
8s, and fell in love with them.

It's an obvious question, since that was their intended use, but it's
amazing how nice they sound when you get right up on 'em. The lack of
bass seems to be less noticeable. The overall balance of the speaker
seems a lot more seamless.

There's a blast from the past. I remember hearing a friend's system
using Time Windows matched with a pair of Randy Hooker subs powered by
Threshold electronics about that time frame. He also had some pyramid-
shaped tweeters on top of the DCMs, but I don't recall who made them.
As I recall he also had a Micro Seiki turntable. It sounded great.

I remember looking for the Snell, but couldn't find a dealer at the time.

Looking to hear the TIme Windows (after discovering The Audio Critic and
reading their love of them) led me to a very interesting fellow named
Randy Cooley who owned/owns Optimal Enchantment in Santa Monica. I
think that it was called something else at the time. He was a hippie
type of guy, super friendly. I listened for hours and the Time Windows
seemed like magic to me at the time. Later I also bought an Oracle
TT/Alphason arm/Dynavector cartridge from him. He was a neat guy and
very helpful. Years and years later, I saw and talked to him at the
Stereophile show in LA (two years ago?). We chatted and chatted like old
times. He introduced me to Richard Vandersteen, and I liked him as well.

I'm probably the only audiophile who doesn't care for the LS3/5a.

It was originally designed as a near-field monitor speaker. It was never
intended for home use.

It has a lot of problems, of which limited bass extension is one. The
mid/bass driver (I forget the KEF model number) was made of bextrene, which
is rather dense, which does nothing for clarity or transparency. And when
you turn the volume up, it sounds as if Something Terrible Is About To
Happen.

I used to know the folks at Transduction, Ltd, who did the handled the
importation of IMF Electronics products. (If you guys are reading this,
please get in touch. I still miss you.) They designed a slightly larger
system using the same drivers that could handle huge amounts of power and
play at very high levels without strain. Its only problem was a bit of
midrange "boxiness". (They had a small floor speaker that cost about half
the price of the KEF 105, and was overall a better speaker.)

Small speakers have a number of real advantages, of which reduced
diffraction and greater ease of postioning are two. The cabinetry, which can
be a huge percentage of the price of a high-quality speaker, costs less. But
a "serious" system that uses small speakers without a properly designed
woofer from the same manufacturer is not what I would consider a true
audiophile product.

Wouldn't you appreciate a speaker manufacturer who simply faced up to
the fact that subwoofers now exist, and are really very good? That
means they could forget attempts at bass extension and concentrate on
getting the upper bass right. That in turn would make integration of
the sub into the overall response vastly easier.

The problem is that the low end corner on the LS3/5a is so high that
it would be a "woofer" and not really a "subwoofer" with the crossover
point being so high that you'd lose bass imaging and have trouble even
getting phase coherency.

I diasagree with Mr. Sommerwerck, though. The LS 3/5a has just gorgeous
midrange and it is marvelous to work on... it does a very good job of
producing a convincing imitation of the human voice. This is a difficult
job for any speaker to do, and it's what the LS 3/5a was designed for.

It was never designed for use at high levels, and it was never designed
as a full-range speaker. But it's a great little monitor for mixing,
especially if you're mixing dialogue. I wouldn't want one in my home,
but it's not _for_ that.

Yebbut that is a very old design. I was thinking of modern small box
designs that while they may go down to 50-60Hz are clearly struggling.
They compromise power handling by the sheer excursions expected from
the cone.

It was a full-range speaker in that there was no sub for it. It is
just that full range for broadcasts of the day wasn't expected to go
very low; no home had a system capable of dealing with that. It was
designed for a control room in a truck, and for that it worked very
well.

Good point.

Part of the problem is that speaker designers insist on efficiency and bass
extension above good transient response, and have switched back from
acoustic-suspension (2nd-order) designs to ported (4th-order) designs. This
does not help the quality of the mid-bass, nor does it make it easy to get a
good transition from the woofer to the satellite.

The "correct" way to design a woofer -- particularly if it's going to be
used with a matching subwoofer -- is an overdamped 1st-order design.
Overdamping gives superior transient response, _more_ output in the octaves
below the corner frequency, and permits phase-coherent mating with a
subwoofer having a simple 2nd-order low-pass rolloff.

By the way, the term "sub-woofer" is universally misused.

You're agreeing with me. The LS 3/5a is a _monitor_ speaker.

If you can't hear the fundamental on the lowest note on Jaco Pastorius'
bass, it's not a full-range speaker. If you can't hear his bass at ALL,
it's a "restricted LF" speaker.

If the tympani on Dorati's recording of Petrouchka bottom the drivers out
at well below normal listening level, it's not a full-range speaker, not
even a little bit.

I had a bad experience with Randy a number of years ago. He was using
a turntable on top of a really high stand (over five feet tall!), and
I walked up to see what it was. He actually told me not to breathe on
the turntable. I turned around and walked out. To be fair, others
have told me that he's a great guy. But he blew it with me.

I heard the DCMs at Havens and Hardesty in OC when I was still a
teen. The audio salesman who demonstrated them was actually blind.
Nice guy, too. We listened to the DCMs for a while, and I wanted
them. At $747, they were a bit too pricey (I had $500 to spend). I
looked over and saw the Snells and asked about them. The salesman
said something to the effect, "Oh...I think you're really going to
like these." I did. They were $550 a pair. I told the guy I only had
$500. He said "Sold!" He even threw in the stands and the wire.

I enjoyed those for many years. I finally blew out the tweeters one
day and gave them to my older brother. He had them fixed and is still
using them. I always thought the Js were the forgotten Snells. I
remember feeling frustrated because Stereophile reviewed every single
Snell except for the Js. I had just started reading Stereophile and
wanted validation, I think.

Funny thing is they're still being made, in a way. The Audio Note AN/
J is basically the same design. The prices range from about $2500 to
$19,000 a pair. That's a long way from $500.

IMF used the B110 as a midrange which increased its effective power
handling and, in their biggest versions, gave it a more generous and
separate enclosure. (I built a similar arrangement.)

Never seemed to hurt the general perception of any of any number of speakers
that used it as a midrange.

> And when you turn the volume up, it sounds as if Something
> Terrible Is About To Happen.

That's what happens when you try to use a midrange driver as a woofer. The
source of the problem you've noted is lack of XMax. From what I can read,
KEF did eventually upgrade this driver to the point where its Xmax was up to
modern standards for a driver this small.

They probably used modern variants of the B110 and T27.

Midrange boxiness - that might be the historic peak around 1 KHz that could
be made to go away by tuning the crossover a bit.

Making a speaker small doesn't reduce diffraction, but it does change the
transition frequency. As far as positioning goes, that can mean many things.
In my view, very small speakers are hard to position because they lack
directionality, That makes them engage the room more, which in turn makes
them hard to position. An alternative view would be that because small
speakers lack directional control, you don't have to aim them carefully to
get sound where ever you are in the room.

Agreed. You're echoing your origional quite agreeable claim that the LS3/5a
was never designed for general home use. However, it could be a pretty fair
match with a really small room.

There are better plastics. Not to mention Kevlar.

Not necessarily. Transduction Ltd used the same driver in a slightly larger
enclosure, and it did not have that problem.

I remember giving a demo with a huge Audio Research solid-state amplifier
(about 350W/ch), and during a peak in which the amp's power meters nearly
pegged, * the T2 had no problems.

* It's not clear what the power meters on solid-state Audio Research amps
actually measure. But one can assume that a near peak in this case must have
represented perhaps 100W, at least for a second or two.

I'm thinking more in terms of positioning the speaker with respect to the
walls, the listener, and (to some extent) the floor. Small speakers have an
advantage here.

We could get into a long argument here, but it's my view that speakers tend
to have broad dispersion, simply because -- ignoring the theoretical "ideal
point source" -- it's easier to get broad dispersion than controlled
dispersion.

Which -- coming back to the original point -- is what it was designed for.

I find mine extremely useful in a small room at close proximity, and have
nicely aligned drivers, sitting up on the shelf above my workstation. I
don't even find the lack of bass a problem for my use, and if there is a
bass problem it is easy to *see* it (with grilles off). Mid and high

Wow! You're right...it was Audio Today! I used to get the two mixed
up because they were so close together. I did buy speaker cable from
Havens and Hardesty a few months later...Kimber 4TC. The Snell Js
were bi-wireable, and I wanted to experiment.

It may not have been the identically same bass driver. KEF made a lot of
changes to the B110 over the years. The later ones are said to have 6 mm
Xmax, which is OK for a woofer of that size.

You mean actual analog meters? Those are for impressing visiting firemen. I

with my DAW.

Depends what you call an advantage. For the most part, I favor making the
performance of the speaker as independent of the room as possible. That
means directionality control, and that disfavors small diaphragms.

I agree with where you are headed, but I'd say it differently. It's easy to
get indiscriminate dispersion, because after all, its well, indiscriminate.

I have some friends like Earl Geddes

http://www.gedlee.com/downloads/Cum%20laude.pdf

and another less well known who strongly favor waveguide speakers - horns to
the unwashed. The actual sound of their systems is the best testimony to
the validity of their technology.

Doped paper, perhaps.

We could argue this ad nauseum, but one of the desirable properties of any
cone material is "deadness". Electrostatic and planar-magnetic drivers
largely sidestep this problem.

No, actually, the 1812.

ARC was never interested in gimmickry, so I often wondered what the purpose
of the output (I was about to write power-output, then removed "power")
meters was. They weren't calibrated. I can only guess they were to warn the
users of possible overdrive.

I agree that, if you're going to have some indication of output level, LEDs
are better than analog meters, but they still leave a lot to be desired, as
(basically) they show nothing more than (maybe) peak clipping. It would be
nice to know how much current is being drawn. Or even better, phase angle.

Crown did some good work in this area. They had a system that dynamically
reduced the amplifier's gain as the output transistors approached their safe
operating area. (They had a way of measuring the safe operating area of
output devices without destroying them. Each amp had a matched set.)

They also had a circuit called the Input-Output Compartor, stuck in the
feedback loop, that showed when the input and output voltages differed in
magnitude more than 0.1% or something like that. I might add that the IOC on
the K-1 amps I had never came on, but the amplifier still sounded awful.

The problem is that, although controlled directivity is highly desirable,
it's extremely difficult to do, precisely because a uniformly directional
driver has to be much larger than the wavelengths it reproduces, and such
drivers wouldn't be good reproducers of those wavelengths. Small diaphragms
permit broad dispersion over a wide frequency range, and are thus more
"practical".

Bud Fried experimented with controlled dispersion in his larger IMF
speakers, but eventually abandoned it.

Arny, you tend to reject planar speakers, but one of the advantages of a
long "ribbon" driver is that it works _with_ the floor and ceiling
reflections to reduce room interactions. Lateral problems can be handled
with a bit of acoustical panelling.

Describing a driver's dispersion as "indiscriminate" strikes me as an
example of the pathetic fallacy.

I haven't heard the current crop of horn speakers. Klipsch made some pretty
atrocious products, which have biased my view of horns for many years.
(Klipsch was, in at least one way, a loony. He seemed to think that, as horn
loading was the best way to design a driver, that any horn driver was ipso
facto a good driver.)

I'm going to ask Mr. Geddes some tough theoretical questions and see what he
says.

I've browsed this article, and will return later to give it a careful
reading. But I already see one fundamental fallacy -- that room acoustics
_always_ swamp the sound of the speaker itself. That is, what we hear is
always the sound of the room, and never the sound of the speaker. Therefore,
any speaker that works correctly with the room will necessarily be an
accurate reproducer.

I need to read more. Thanks for bringing this to my attention.

The midrange is phenomenally more accurate than the M-Audio boxes. The
LS 3/5a was designed as a near-field monitor and it does a great job in
that application.

I don't think so. IMF, prior to being operated by
Transduction, Ltd., used KEF/Celestion drivers
such as the B110 that was in the LS3/5a. Later,
Transduction sourced their drivers from ELAC.
They looked similar and, amazingly, performed
similarly.

In addition, there were many concurrent variants
of the LS3/5a from different manufacturers and
not all of them used the same KEF drivers. AFAIK,
BBC specified the size/configuration/performance
but not the actual composition. As long as it
conformed as tested, it could bear the LS3/5a

At the time I knew Transduction -- 1978 through 1980 -- they used KEF
drivers.

This is possible. We sold LS3/5as (I don't remember the brand), and they
were pretty bad at playing at high levels. This isn't surprising, as they
were never intended to.

I believe in some (all ?) instances LEDs require correct 'calibration'. I
have an amp in which, "out of the blue", one of the 2 channel's LEDs flashed
way too prematurely. It got fixed when the amp received some other repairs.
I'm with the "visiting firemen" because at times looking at the analog
meters I become informed of a problem before I actually notice it. "What did
you say?"

They do but they don't. The materials the diaphragms are made out of is
fairly resonant, but the diaphragms are usually so thin that it doesn't
matter.

On the topic of paper, anybody who wants to can comment on the resonant
properties of a dried pile of paper mache. ;-)

Now that SS amps easily capable of driving 2 ohm loads are common, the whole
reactive speaker load issue has largely become moot. Yes, a 2 ohm load line
passes through zero current and voltage at the same time, but the other
places it goes will give heartaches to amps that don't do well with reactive
loads.

It must have been broken. The opposite is true of some modern amps. Their
clip lights come on and the amp still has like 0.02% THD @ 20 KHz. The
trigger circuit is just that hyper-sensitive.

Controlled directivety with direct radiators can be approximated by using
more drivers each covering a narrower frequency range, such as was done in
the NHT 3.3 .

If you get say 90 degree controlled directivity, its pretty much good
enough. That does not require a driver that is "much larger" than the
wavelength it reproduces.

The "do it right approach" involves waveguide speakers, known as "horns" to
the great unwashed.

It's not the ribbon, its the effective length of the diaphragm. People have
built line arrays and carefully controlled the phase of the drive to each
driver, with some pretty amazing results. This approach is costly, even by
high end audio standards, so not many high end speaker manufacturers have
tried it.

Actually, it takes quite a few square feet of that in a typical midwest

That may have been the transition from the old IMF production under

But this is what Dr. Geddes' article implies. He says his Summa Cum Laude
system (a _bad_ name for a speaker -- it lends itself to vulgar jokes) is
perhaps the best speaker in the world. But he gives no justification for
this, other than the claim of "correct" room interaction (most of which
makes sense to me, and I don't disagree with -- the section on room
reflections fits with what I think I understand about such things, and is
worth studying), and the overall flatness and smoothness of the speaker's
measured response.

But he never says anything about the system's drivers. His is basically an
enhanced/extended Klipsch point of view -- if you get the dispersion right,
the speaker must necessarily "sound good". Though one would expect a speaker
with the measured response of the Summa Cum Laude to be at least
pleasant-sounding (I'd be flabbergasted if it _weren't_), it doesn't
automatically follow.

The reason I'm so emphatic on this point is that most (if not all) the
people in this group have never heard a plasma speaker. I have. When I
worked at Barclay Recording & Electronics, Dr. Alan Hill twisted our arms to
carry the Plasmatronics -- which, 30 years ago, cost a startling $8000/pair.
Dr. Barclay was an avid live recordist, and we played his master Nagra tapes
through the Plasmatronics. To quote Herb the K (in another context) --
"Everything else is gaslight." It is the only speaker I have ever heard that
actually sounds REAL -- as if you're actually hearing live sound. *

Yes, yes, yes, yes, yes, yes, yes... The Plasmatronics used French bextrene
mids and woofers that weren't within light-years of the performance of the
ionic driver (which worked from 700Hz up). And the discontinuity was
audible.

But -- the difference in sound quality was plainly -- grossly -- audible in
a room full of other loudspeakers, none of which (including the
Plasmatronics) had been designed to work "with" (or independently of) a
room. If Dr. Geddes had a chance to hear the Plasmatronics, his view of the
relative importance of the "absolute" quality of a speaker versus the way
that quality is degraded by room acoustics might find itself being adjusted
a bit. Quite a bit.

Simply put, the absolute (and relative) quality of speaker systems _is_
audible in rooms with "decent" acoustics. This isn't to say that further
improving the room acoustics towards some ideal, or paying more attention to
some of the points that Dr. Geddes raises, wouldn't further improve the
sound. But listeners don't prefer planar speakers simply because they
interact "differently" with the room. Dr. Geddes really needs to address
this point of the quality of the drivers in the Summa Cum Laude. What are
they, and why were they selected? Inquiring minds want to know.

Dr. Geddes also makes a statement that brings into question his listening
ability and judgement. **

"CD [constant-directivity] is a well know[n] design criteria [sic] for large
venue systems, but it is almost nonexistent in home high-fidelity
loudspeaker systems. There are two reasons for this; pistons and size.
Piston sources can never be CD and CD simply cannot be done in a small area.
It takes space and area to control sound radiation and there is simply no
way around this fact. Hence, for sound systems in small rooms, bigger really
is better. Somehow it just seems obvious that the larger speakers of the
past sounded better than the multitude of mini-cubes and tower speakers of
today. Small speakers do have their place, but not as sources for critical
listening in a well designed room. Virtually all small speakers are
omni-directional. It’s easy and inexpensive, but completely wrong for a
small room."

I assume the kind of "larger speakers" that are so obviously better sounding
are of the Bozak ilk. These had (by modern standards) large drivers with
poor dispersion, and sometimes included vertical arrays of mids and/or
tweeters. Such speakers have a wonderful "in-your-face" quality -- you crank
up the volume and you are submerged in the sound. Great fun.

But when you listen critically to such speakers, with good program material,
it's obvious that the modern speakers Dr. Geddes is so quick to decry are
more-accurate reproducers. They simply sound more like the signal that's fed
into them. They can also be insufferably insipid-sounding, but that's,
perhaps, another issue. (They needn't be. B&Ws are both accurate and
non-insipid.)

Perhaps I'm being unkind in saying so, but Dr. Geddes doesn't seem to be
very interested in the absolute fidelity of his speakers. He does seem to be
the sort of designer who fixates on one thing, and thinks if he gets it
right, he's gotten everything right.

His paper conveniently overlooks the gorilla in the room -- LEDE. LEDE
reduces or suppresses early reflections, while allowing the listening area
to be filled with long-delay reflected sounds. Why is altering the speaker
to fit the room necessarily better than the opposite? Dr. Geddes doesn't
discuss the relative merits and demerits of his system and LEDE, nor are
there any comparative listening tests.

Though I appreciate the paper's conversational style, it isn't particularly
well-written and suffers from typos and other problems.

> But, any good speaker that works well with the room
> it is in is miles ahead of the common alternative.

Dr. Geddes' point of view seems to be that a speaker that doesn't work well
with the room is, by definition, _not_ a good speaker. I have no argument
with Dr. Geddes' technology -- it seems to achieve the desired ends, and
they are, in and of themselves, good ends.

I am simply saying that the kind of directional playback he advocates is
_not_ more important -- or even _as_ important -- as the basic fidelity of
the system itself. Nor is it a guarantee of accurate sound reproduction.

* I was speaking with Dr. Barclay the other day, and the Plasmatronics came
up. His opinion was the same as mine, and had not changed in 30 years.

** Even if he _is_ a bad listener, that doesn't invalidate the design of the
Summa Cum Laude.

Implies would be a good choice of words - it suggests that one could read

He's never said that in my presence, or the presence of other signficant
people in Detroit. ;-)

In my view, his speaker system has considerable merit because it does have
an intelligently-designed radiation pattern. Geddes probably has an
exceptionally good handle on what a good radiation pattern is, and how to
design waveguides to obtain it.

> But he never says anything about the system's drivers.

The unique technology is the waveguide that he puts in front of the
compression driver. Everthing else is pretty much off-the-shelf.

I would say that Earl believes that if you get the radiation pattern and
power response right, and low nonlinear disstortion and good efficiency and
power handling, you've got a lot of goodness. BTW, getting the radiation and
power response right implies getting the on-axis response right.

They are. And, they are tolerant of differences in rooms. In his home, he
has a pair in a sparsely-furnished room with a hardwood floor and plaster
walls. He has 3 more (LCR) in a room with very carefully-designed acoustics.

I have to. I heard a pair at Dr. Hy Kichalsky's house. Hy was the founder of
The Audiophile Society (of Westchester County).

Hy's Plasmatronics sounded very good, too.

That's impressive, but in the larger context I don't and can't know exactly
what it means.

Or not. To me a relevant experiment involved moving a variety of better
speakers around to a number of listening rooms, and of course listening to
them in each room. The group conclusion was that the speakers tended to
sound more like the rooms they were in than any unique identity that the
speakers had.

Of course, different speakers, different rooms, perhaps different
conclusions. But the result involved enough different rooms and speakers
that it was very convincing.

I don't think you can fix a miserable room with a good speaker. I do think
there are some rooms that are so miserable that no general-purpose speaker
can sound good in them. I know that in most rooms, most speakers sound
different and some are preferable than others. I know that if you change the
room a lot, or pick a different room, your favorite speaker of the same lot
may be a different speaker. And, I know that certain speakers that are
inherently highly tailorable can sound amazingly good in really bad rooms.

Agreed.

I don't see planar speakers as panaceas, and I don't see preference for
planar speakers or a certain planar speaker as being some sort of audio IQ
test. OTOH, the right Magnapans, the right room, and the right music can be
quite a treat.

The drivers themselves are not exceptional. They are good drivers and they
are competiviely priced for what they are. Geddes favorite kind of magic
would be the design of the waveguide (horn) for the upper-range driver.

Wide range CD speakers are necessarily large.

Right, and if you are in a really small room, you probably want to go down
the near field or even headphones road. Ironically, Geddes did a lot of his
early development of his ideas and technology for a certain large automotive
manufacturer. His ideas were not always ideally applicable to that context.

I think someone is taking a swipe a Bose, which is not a bad thing to me.

Again, that is particularly true if the small room is rather reverberant.

BTW, any reader of this post should note that the quote from Geddes ends
right here.

I don't think so. I think arl might be thinking of something like Altec
A-4s, or some of the large JBL Pro systems designed for monitoring.

Well, the vertical array of tweeters does sound like the bigger Bozaks, but
that's you talking William, not Earl.

But that's a comparison to the large speakers of your choice William, not
Earl's.

That would be your perception William, not the Earl Geddes I know.

LEDE is yet another idea that is good in some circumstances, but LEDE is not
a panacea. I know what Earl's preferred design for a listening room is, and
no way is it LEDE.

Controlled directivity is also a good idea, but it has more generality. I
comes closer to be a panacea, given that the best solution always involves a
room with the best possible acoustics for reproduction of music and spoken
word.

I think you've added an omission that is not really there. Earl thinks that
the basic fidelity of the system is based on the things I listed before,
headed up by power response and directionality.

There are no guarantees. ;-)

What I intended it to mean was that the difference was plainly audible,
despite the less-than-ideal listening conditions..

That hasn't been my experience, but I've never done such and experiment, and
I've often treated the rooms I've lived in. There is no question that a bad
room will swamp the subtleties of any particular design.

Of course not. That isn't the point. My point was that in a "decent" room,
significant speaker differences _are_ audible.

I've heard rooms so bad that I wonder whether Dr. Geddes' design would work.
(Untreated basements come to mind.) You still have to dampen the room some.

JGH used to claim that dipole speakers were _more_ sensitive to room
placement, and this made them easier to get "sounding right" -- if you spent
the time adjusting them. I don't know if that's generally true.

The original Maggies could be spectacular in their rounded-off way, but as
they got more accurate, they became less pleasing (to me). And they're not
true planar speakers, anyway. (Honesty compels me to admit that one of the
reasons -- though hardly the principal one -- I don't care for Maggies is
that I don't like the way they're marketed or sold, nor do I care for the
religious beliefs of the people manufacturing them.)

No argument, but he wasn't. JGH -- the only reviewer who saw through the
901s, and attacked accordingly -- was remarking to me the other day just how
spectacularly spacious they could sound when mounted near the ceiling.

Bose has popularized the "mini-cube" more than anyone else. I've never heard
them, and am not sure I want to.

I wouldn't disagree, but this raises the issue of whether you should damp
the room acoustics.

No offense, but he should have named names. Are the JBLs, et al, still
considered highly accurate speakers? I don't think so.

I didn't claim it was a panacea. I said that it was an approach that
attempts to do the same things Dr. Geddes' approach does (suppress early
reflections, surround the listener with long delays, etc). It therefore
needs to be discussed.

I got the impression he was. Regardless, LEDE forces consideration of that
dichotomy.

Then he should write a longer one! <grin>

Because there are many excellent -- ie, accurate -- speakers that aren't
designed to work _with_ the room. In order to get good sound, you have to
treat the room, set up the speakers carefully, etc.

He doesn't discuss it in the paper. And I find this critical, as he is
claiming the Summa Cum Laude is "perhaps" the world's best speaker.

I'm damned if I am going to read this long thread which can only be
circular, starting at where the LS3/5A is a nearfield monitor as
William says, and perforce ending with nothing more being expected
from a nearfield monitor than what it is intended to provide, which is
*not* high levels of headbanging bass.

But I do want to make the point that the LS3/5A was for a long time a
cheap alternative for classical and especially early and chamber music
lovers, and even more particularly for lovers of the human voice, who
could not afford horns from Lowther or electrostats from Mr Walker.

The LS3/5A should be honoured for that and not measured against
perverse standards retrospectively applied. Any old idiot can be snide
with 20-20 hindsight -- but ask him to design a better speaker for the
same money which isn't the size of my Impresario
http://members.lycos.co.uk/fiultra/KISS%20195%20The%20Impresario.jpg
and watch him fall flat on his face.

Now let us honour famous speakers and true.

There's nothing perverse about pointing out that the LS3/5a wasn't a very
good "living room" speaker 30 years ago, which should have been obvious to
any critical listener. (I realize I'm implicitly criticizing JGH, who's a
good friend, but I have to say it.) I didn't like them then, and said so.

And, as I pointed out, Transduction showed that you could make a much better
speaker with the same drivers, if you were willing to use a slightly larger
cabinet.
