From text I sent to Stereophile
I have been a subscriber for about 15 years. In that time I have=20 learned, and tried to put in practice, good room treatment techniques. I=20 use test CD's and a sound meter to aid in placement and I treat all the=20 room hot spots like first order reflection, echo flutter and deaden the=20 area behind my head (my Triangle Celius speakers sounds their best in a=20 spot that forces me to the rear wall- I have an odd room). What confuses=20 me is the double speak on tone controls and equalizers as well as=20 exactly which test tones I should use when running the tests. On equalizers/tone controls. I can't count how many times I have read=20 that these are either the bane of our collective electronic existence or=20 a necessary tool to help make some recordings sound right (specifically=20 tone controls). On equalizers I read that they induce too many problems=20 but your magazine has recommended several of them (all in the digital=20 domain I believe). In my room I have several strong nodes below 300hz (as do most people I=20 am sure). I have a small dent at 50hz, huge plus ups at 60hz and 120hz=20 and a dip at about 250hz (Here is where the test tone confusion comes=20 in. With warble tones the aberrations are far lower. With straight tones=20 I have a 16db shift from 120hz to 250hz - with warble tones the shift is=20 about 5db. Which am I to use?

But the system itself will be basically=20 playing flat into your room, just as the quartet live is playing "flat"=20 and sounds perfectly real without even any EQ! So set up a reasonable=20 system, get a good balance between your mains and your subs, between the=20 fronts and the surrounds, and enjoy the music! If you didn't need any=20 fancy digital room correction for the live music, you don't need it for=20 the reproduction either. And remember, EQ is not supposed to be flat at=20 the listening position.

Finally =96 does anyone make an
affordable analog EQ that only affects the range below 300hz? (Or a digital unit that is affordable and isn't meant for subwoofers?) I use a Rane 1/3 octave equalizer. I have several sub-woofers and find that corner placement is NOT a good choice (in my room). I use considerable boost at 40 and 50 Hz and cuts at 80, 100, and 120. Again, this works for MY room. The Rane equalizers are not too expensive. ---MIKE--- In the White Mountains of New Hampshire (44=B0 15' N - Elevation 1580') |

I find you need 1/3 octave control to make it work well usually.
1/5 octave is better. And I am referring to using warble tones. I would EQ to the listening position. You don't want to boost dips in response too much. I usually limit it to 6 dB. I drop peaks as much as needed. I find it makes a fair amount of difference when done. I use software to make 1/5 th octave warble tones. Measure the speaker up close and at the listening position. Helps you figure out what the room is doing. I then EQ digitally with software to flatten things out. Seems to do a good job. Just not convenient. Using this approach you would need to EQ and re-burn all your CD's if that is your source. A piece of consumer digital gear to give you this control would be extremely useful. Dennis |

I haven't heard them in action, but Behringer makes a line of equalizers and
most interesting to me, three-way crossovers, some of which have adjustable equalization and time delay which I hope to test with my JBL S8R fairly soon (using two Hafler 500's and a Halfer 225 for the amplifiers - my neighbors will probably hate me). neIed the time delay because there is no way to mount a 375 with either the 2350 horn or 2309/2310 horn/lens assembly (to get a 500Hz low horn cut-off) in the same plane with the LE15A bass driver and 075 tweeter. The most popular 1/3 octave equalizer in the 70's was made by Soundcraftsmen, and I've seen one on eBay recently.

This is because of the huge advances made in the RCS 2.2. There was a time when you could get a RCS 2.0 upgraded to RCS 2.2, sadly this time has now past, (unless of course you actually mean this upgrade by the word 'refurbished') IMO once you've heard the RCS 2.2 there is just no going back! May I just add that customer support from TacT is truly excellent. I don't own TacT RCS myself but have been greatly involved in the setting up of friends TacT based systems. -=Mike=- |

Hi Mike,
A few notes: Although the TacT RCS 2.0 is very good there is a valid reason why they can now be got for less than half price. This is because of the huge advances made in the RCS 2.2. That's an "RCS 2.2X", not the discontinued "RCS 2.2". Don't buy an RCS 2.2 - it's too old. There was a time when you could get a RCS 2.0 upgraded to RCS 2.2, sadly this time has now past, ... Tact was going to offer a 2.0 to 2.0 mk II upgrade, but couldn't get the chips for it. They now have an RCS 2.0S that offers the same performance as the RCS 2.2X, but without the sub channels. A used or refurbished RCS 2.0 is still a very good device, and an excellent value for the money. ... IMO once you've heard the RCS 2.2 there is just no going back! With the 2.2X, you can add corner-woofers like the Lyngdorf (nee Tact) W210's and get fantastic bass. Even if you have no desire to add subwoofers now, you will once you learn what room correction can do. Without the RCS, you're the room's bitch. With the RCS 2.0S, you're putting up a fight. With the RCS 2.2X, the room is your bitch. May I just add that customer support from TacT is truly excellent. There also is the Tact Audio Users Group (http://groups.yahoo.com/group/TacTAudioUsersGroup/) for beginners to advanced users. BTW, don't let the advanced users and modifiers scare you off - we may have our complaints but you'd have to rip our RCS's from our cold dead hands to get it away from us. I have the RCS 2.2X, a pair of the S2150 amps, and a pair of the W410 corner-woofers. Regards, Tip |

My new Linkwitz Orions already go down to 20Hz so I don't plan on adding a sub. The refurbished RCS 2.0, at $1500, was already the most I was willing to spend for a new preamp. Has anyone actually done a blind test of the 2.0 and 2.2X using the same room curve? I wonder how much, if any difference there really is. Tim McTeague |

Hi Tim,
I was wondering how much the newer models added other than subwoofer control. The subs are only on the RCS 2.2X. The RCS 2.0S has twice the frequency resolution of the RCS 2.0, but that's not a big deal. My new Linkwitz Orions already go down to 20Hz so I don't plan on adding a sub. The advantage of the sub channels of the 2.2X is that the subs, or preferably corner-woofers like the W210's, can be placed in the front corners (if you've got them). I have B&W801's, which aren't bass-shy either, but adding the W410's made a huge improvement in the bass because of the corner placement, which is the best place for woofers but only if there is DSP correction. Next best is dipole woofers, but they don't work in corners. Stick a Thor in each corner. The refurbished RCS 2.0, at $1500, was already the most I was willing to spend for a new preamp. Has anyone actually done a blind test of the 2.0 and 2.2X using the same room curve? I wonder how much, if any difference there really is. I had an RCS 2.0 before I got the 2.2X, but I didn't compare them because I also added the W410 corner-woofers, which made an order of magnitude difference. But I wouldn't tell you to upgrade from the RCS 2.0 to the RCS 2.0S. I sold my RCS 2.0 for $1900 three years ago, so I think you got a great deal. Regards, Tip |

As my current setup far exceeds the quality of anything I have ever heard before I can't imagine much improvement. Some DVD movies, however, can cause the power amp to clip during super low frequency stuff so maybe a 2.2X and pair of Thors are in my future. For now I am happy camping. Tim |

People try so hard to get that absolute flattest response in their room, but really, they should simply achieve the best balance. I say to simply move your speakers around in the room untill you find a spot where the speakers seem to come "alive." That's it. Any EQ or tone controls added afterwards should be mild, plus or minus 4 db. Then you're good and all is well. It's not perfect, but its' probably perfect for that room or very close to perfect, and, ultimately, you'll be happy. CD |

Any tool can be misused and some lend themselves to misuse. Tone controls are most effective for source correction, not room correction.

(I should also note that I heard no negative artifacts with the EQ - no imaging change or high frequency issues). Your preference for using the warble tones over the extended pure tones is probably right. Even better are gated sweeps or pulses but you need appropriate software for those. So far as deciding whether it is better to make a seemingly subtle EQ or eliminate the EQ and live with the 'bloat.' only you can decide. I would suggest, however, that A/B testing can help you with discerning the difference but is less useful, for psychophysiological reasons, than extended listening. The difference may be subtle but it is, now, a change from your internal reference. Try living with the EQ correction for a few weeks and then repeat the A/B. Your response may be different. You should also be aware, as you have implied, that trying to correct for a local peak or null may make things a bit worse elsewhere in the room. Ultimately, however, you only have to satisfy your ears and mind, not your graphic displays. Try surfing the room EQ discussions on www.avsforum.com for a lot of heated but informed commentary. Kal |

In this context yes. fact is if they overload the room they will not sound real in the way we want things to sound real. Now, the point of the exercise is to make your room sound good for MUSIC, and let your system simply play in this good sounding room. You couldn't be more wrong. the acoustics for good live music are nothing like the acoustics for playback. For live music, the room sound is part of the performance. For playback that kind of reverb, good reverb for live music, would be terrible. Sure, if there is some ridiculous resonance at some bass frequency you want to dampen it. But the system itself will be basically playing flat into your room, No it is not. frequency responses are measured well into the room and a reverberant room will profoundly affect that response not to mention all the smearing you will get. just as the quartet live is playing "flat" Are they? You think they would sound the same regardless of the space they are playing in? and sounds perfectly real without even any EQ! And in the wrong room perfectly awful. But your premise is painfully flawed. So set up a reasonable system, get a good balance between your mains and your subs, between the fronts and the surrounds, and enjoy the music! That is a good basic formula for the bare essentials of playback. But with time, care and the right equiment there is a lot of room for improvement. That is what the high end is about. your advice is quite right for casual listenes not for audiophiles. If you didn't need any fancy digital room correction for the live music, you don't need it for the reproduction either. Oh that is ridiculous. How can you possibly compare such two entirely different things? The reverb in live music is an intregal part of that music. If well recorded *that* reverb is already there. Adding the everb of yet another room, the listening room for playback is all wrong. It's not the same thing at all. The only way to make listening room reverb work the same way as concert hall reverb is to have a seperate channel for each instrument with zero cross talk from the other instruments, and then have a mic/speaker system that can mimic the radiation patterns of the original instrument, then place each speaker in the room in the same configuration as was the original performance. That would ridiculous. But if this isn't what you are doing then you are simply comparing apples and oranges. Speaker/room interaction is nothing like live acoustic music/room interaction. And remember, EQ is not supposed to be flat at the listening position. Why not. The room gives it a natural taper at the high frequencies, which is part of the deal, so don't go to any lengths to "correct" that. Wrong wrong worng. correct it please. Don't let the room ruin the playback. Gary Eickmeier So well put. People try so hard to get that absolute flattest response in their room, but really, they should simply achieve the best balance. The best balance usually is a flat response. Certainly there are other issues but all else being equal flatter is usually better with speakers. I say to simply move your speakers around in the room untill you find a spot where the speakers seem to come "alive." That's it. Any EQ or tone controls added afterwards should be mild, plus or minus 4 db. I agree with this more or less. You will likely do much better with careful speaker placement and room treatment than you will with EQ. I wouldn't mess with EQ for room correction. If the speaker room interface is sooo bad that it needs EQ I would look to one of the digital room correction devices. They are far more precise and the good ones do more than just fix frequency response. Then you're good and all is well. It's not perfect, but its' probably perfect for that room or very close to perfect, and, ultimately, you'll be happy. Not to be a nay sayer but it takes a lot of work with speaker placement and usually substantial room treatment to get anywhere near the best sound possible from your system. Scott |

Umm...I'm going to let everyone chew on that phrase for a second: "they will not sound real in the way we want things to sound real." What's to chew on? Anyone with substantial experience with live music knows exactly what I am talking about. There is a good reason acousticians are involved in designing concert halls. There are obvious reasons why orchestras don't play in rooms the size of your average listening room. You put an instrument or an ensemble in a room that is not big enough to handle the sound then you will get a sound that is not the way we want it to be. So you will get a sound that is both real and completely wrong. I believe you have summarized the basic problem facing audiophiles [sic] rather succinctly (whether intentional or not!). Hardly. The basic problem most audiophiles face is affording what they want. Listeners don't want "reality"; I think it wise that you don't speak for other audiophiles. Just because I don't like the sound of live instruments overloading a room doesn't mean I don't want realism.Big diffence between realism and reality when reality sucks. The realism I seek in audio is that of live music played in a good acoustic space. Is this idea new to you? they want what they want... I suppose that much is true..... and then they want to believe that *that's* "reality". Wanting what one wants isn't reality? Please explain. you mean I don't really want what I want? odd idea.

Umm...I'm going to let everyone chew on that phrase for a second: "they will not sound real in the way we want things to sound real." What's to chew on? Anyone with substantial experience with live music knows exactly what I am talking about. Okay, well, I've got "substantial experience with live music" and I either still don't know what you're talking about, I thought it was pretty clear, live music in a space that does not serve the quality of the sound. It's both real and undesirable. or (more likely) I know that the semantics of your sentence are problematic. "The way we want things to sound real" has nothing to do with the "real" part, No it has everything to do with the real part. I want realism but i want good quality realism. Live music in a poor acoustic space is real but it is not a desirable sound. Live music in an excellent acoustic space is both real and excellent. That is what i want to hear. Now plese pay attention, I said i want realistic sound just of a certain quality. That *excludes* unrealistic sound. Does that clear things up at all? and is entirely about "the way we want things to sound". No it's not "entirely" about the way we want things to sound except that "we" (I) happen to want realistic sound of good music played in a good acoustic space for that music. See, realism never leaves the picture of what *I* want. Please don't try to twst my words to say otherwise. In fact, if you had just written "if they overload the room they will not sound real in the way we want things to sound" I wouldn't have even bothered replying; that's practically axiomotic, a perfectly resonable sentiment to express. Unless one did want unrealistic sound. Clearly some do. if one likes the sound of playback splashed all over a lively room from drivers pointed in every which way for the sake of gbgger than life imaging and reverb then one does like things to sound unreal. Some people do like this. i don't. But you wrote "they will not sound real in the way we want things to sound real" Yes i know what I wrote. i was being very specific because the previous poster was advocating an aproach to playback that IMO will lead to lesser realism but possibly greater spectacle. Some people may want that spectacular sound despite it's ledder realism. So I dino leave it open to that possibility. OTOH I was trying to close the door on the idea that realism is desirable even if it sounds bad. For me it isn't. If someone records a drum kit with mics that a re six inches away from each drum I don't want to hear that realistically. Hence real the way i want them to sound real. that would be in a good space from a dsirable distance .. and that rightly should set off all sorts of warning flags in any discerning reader... IYO. I'd say they were not 'rightly" set off at all, especially in the context of the thread and the specific post i was responding to. especially one who has "substantial experience with live music". "Real" is what it really sounds like, regardless of whether it's overloading the room. Did I say otherwise? No. The issue is whether that is what you want to hear. Is it what you want to hear? Music played in all the wrong places? Is that the sound you seek as an audiophile? Not me. "The way we want things to sound" who are you quoting? not me. is personal, subjective, opinion, and we're all entitled to that. Who said otherwise? "The way we want things to sound real" is just wishful thinking. No it's not. It's an intrical part of the process of making music. Maybe you think venues are chosen randomly by musicians and recording engineers. i think otherwise. it is not just wishful thinking. some people actually make it a reality and I, as an audiophile, am most grateful for those people. maybe you don't care and any sort of realism pleases you even the sound of music in an overloaded room. It doesn't please me and i am entitled to that opinion. You put an instrument or an ensemble in a room that is not big enough to handle the sound then you will get a sound that is not the way we want it to be. Agreed. (For the most part...I can think of a few exceptions, but for the sake of brevity I will agree 100%.) So you will get a sound that is both real and completely wrong. Disagree. Reality can't be "wrong" if the goal of music reproduction is to reproduce the original event. If we don't *like* the sound of the original event, that's another issue entirely. Well if we don't like the original event, events like music played in a poor space then we think it is wrong no? All I was saying is that. The basic problem most audiophiles face is affording what they want. LOL! Okay, I will happily concede that point! Big diffence between realism and reality when reality sucks. The only difference is that one presumably doesn't enjoy the reality which sucks. That doesn't make it less real, just less enjoyable. Exactly. and if you go back and look at the context of my comments maybe they will make better sense. The realism I seek in audio is that of live music played in a good acoustic space. Is this idea new to you? That's not realism you seek, Whoa, way out of line. Do not speak for what i want please. It is the relism I seek. don't misrepresent what I want. that's just how you define a goal you seek. Whah? Realism of music played in a good space *is not* what I seek but it *is* a *goal* that I seek? An admirable goal...at least if the source material is live music played in a good acoustic space. But what if the source material is computer generated music that was never "played" in an acoustic space at all? Then i don't have any standard by which to judge it. i simply take it for what it is. I don't use that kind of music alone to judge fidelity of playback systems for a good reason. I figured everyone would understand that i was speaking of live acoustic source material strictly in my comments. What if the source material is found snippets of conversation recorded on a noisey subway platform? What if the source material is good music played in a not-so-good acoustic space? In both cases the original event, the reality, will not be the most desirable sound. If you claim you seek realism, then you must accept the reality of those sources. I suggest you read what exactly i claim to seek. On the other hand, if you want all those sources to sound like live music played in a good acoustic space, you don't seek reality, you just seek a specific personal sort of euphony. Again, you seem to fail to see the differences between realism and reality. Yes I seek a subset of realistic sounding playback, that of good sounding realism. If the reality is bad, I'd like the artists and enginees to try to make it better. Wanting what one wants isn't reality? Please explain. you mean I don't really want what I want? See above. I mean that this thing that you want is not the "reality" of the original performance, It is if the reality was right to begin with. it is an idealized event that potentially never took place, and hence is "unreal." you assume that the ideal is unreal. it isn't. The best soundng music I have ever heard was real. That set of experiences does frame my reference for judging playback. No "idealized" events that "never took place" are a part of my reference for ideal sound of playback of live acoustic music. And I do believe that you really want that, I'm not questioning your motivations. people believe all kinds of things. Scott |

Scott, you get points for tenaciousness, but you still seem to be
conveniently ignoring the gist of my comments. All I'm saying is "the way we want things to sound real" is not the same thing as "the way things really sound". It is however exactly the same as "the way we want things to sound", so there's no reason to add that additional word "real" as if it were a qualifier. If anything it only obfuscates the point. |

IMO people who are splashing their playback all over the listening room , basking in the reverb and enjoying it, want unrealistic sound. That was the jist of my original point. I'm not one of those people. I think listening rooms are critical and are in no way analogus to envirements made for the playing of live acoustic music. And don't forget it is quite possible and unfortunately fairly common to get real sound that is not what we want in the way of sound. Scott |

emfbi, but...
There is really no such thing as real sound in a listening environment except in the original environment where the sound or music was created. Consider the argument in Plato's discussion of "the cave" in The Republic. People in the cave saw shadows cast by their fire, thinking those shadows were the reality, not the people or forms whose shadows were being cast. It's the same thing with music reproduction. We may have an ideal of "reality", but all we can achieve, no matter how good, is a "shadow." Clearly, no matter how fine the equipment and room conditions, there is no way a 100 piece symphony orchestra is going to sound "real" when squeezed across a 15 foot wall. Now, if you are talking dynamics, timbre, sound frequency, that is something which existing high end audio equipment can come very close to reproducing. But, even that will only be an approximation of an original sound source. Sherm wrote in message ...

Scott Or, to put it more succinctly, the best we can hope for is the most realistic interpretation of the actual performance. CD |
