Which speakers use reflected sound?

[Moosebumps]

I am interested in this design principle, and am wondering which speakers
besides Bose have drivers that are not meant to fire right at you. I just
saw a pair of cheap $100 computer speakers that had side-firing drivers,
which I found quite interesting. Are there any good articles about this or
websites which compare such speakers?

all "bipolar" speakers, as, for example, made by Definitive Technology, PSB,
Energy, and others.
By design, all bipolar speakers more or less symmetrically emit sound in
both forward and backward directions. However, the ratio is 50/50, not 18/78
as with the Bose 901.

All "dipolar" speakers emit a backwave that is out of phase with the front.
This is actually intended, or alleged, to reduce room reflections, not
increase them. What actually happens depends upon room placement. In the
particular way I have my Acoustats set up, room effects appear subjectively
to be very much reduced.

I've had the same experience with my Martin Logans - another dipole. In
addition to conventional dynamic speakers, electrostatic speakers made by
Acoustat, Martin Logan, Quad & Sound Labs, as well as planar magnetic speakers
made by Magnepan (Magneplanars) and Eminent Technology have a dipolar radiation
pattern.

Do any of those cost less than the Bose 901's and are easily available to
try out locally in most places? Everyone says Bose is a bad value -- so I
want to try some speakers that are cheaper than the 901's. But I would like
them to place more importance on filling the room than super accurate
imaging. I like it when the speakers disappear, and I like to be able to
walk around when listening to music.

I'm going to use the speakers primarily for music, and the occasional movie.

There are a number of Magneplanar speaker models that are less expensive than
Bose 901's. Also the Eminent Technology LFT-VIII hybrid planar speaker is less
expensive and a very fine sounding speaker. To find dealers for these products
in your area, I would suggest you first go the following websites:


www.magnepan.com

and

www.eminent-tech.com


Both manufacturers make excellent products at reasonable prices. In addition,
Eminent Technology makes planar computer speakers under both its own brand name
and through one of its licensees, Monsoon.

First, almost all speakers use reflected sound to some degree or
another. Bose 901s simply use more by putting most of the drivers in
the back.

Second, you can acheive some of this by simply aiming regular
speakers off the side walls or putting a pair on each channel
back-to-back.

I remember when I first heard the F's. Truly amazing. I was very
impressed. I didn't do a serious evaluation at the time (lack of $$$ and
I was picking up my VPI at the time), but did have them on my "dream"
list. Much better than Bose. Bose 901's would be "ok" if they sold for $500.

hey moosy.....you have got to check out their site AND look at the
reviews...the review on the Walsh Micro is EXACTLY what you are talking
about......you can get a vintage pair on Ebay ,,,,,of the Walsh 4's no less,
for about $650-700 shipped.....it's sort of like the old can't carry his
jock comparison.....or Ruben vs Clay....one really sounds good and the other
is what everybody tells you sounds good but you really don't like it....
