[This is an updated version of a commentary written in 2009.]
The latest Mapleshade catalog (Spring 09) has, along with hundreds of recommendations, this little piece of audio advice that caught my eye:
For much improved bass and huge soundstage, put your listening chair or sofa right against the wall behind you. Move your speakers in to 5’ in front of you and 7’ or more apart. No room treatments will yield this much bass improvement.
I literally had to read through it a couple of times to be sure I wasn’t hallucinating. But every time I read it, it still said the same thing, so I know I can’t have been dreaming. This is crazy talk. What the hell is wrong with these people?
Well, it’s not all crazy. There is actually a factually true statement at the end of that paragraph. Yes, it is true that no room treatments will yield as much bass as sitting up against a wall. But why stop there? Bass, regardless of its source, immediately seeks out the corners of the room. That’s where the most bass will always be: where the room boundaries are. If you want to hear the maximum amount of bass your speakers are producing, put your head in the corner of the room down at the floor, where three boundaries intersect. Like the sound now? Getting enough bass are ya?
Along the same lines, for a “huge soundstage” try putting one speaker at one end of the room and the other speaker at the opposite end. Why stop at seven feet? My listening room is twenty feet deep; I can get a soundstage that’s twenty feet across without any problem at all.
I would just have to be dumb enough to think that doing such a thing would be a good idea.
Fellow audiophiles and music lovers, it is not. Let’s talk about why.
The closer you are to anything that the sound coming from your speakers can bounce off of, right before or right after it reaches your ears, the worse the sound. You want to be as far away from everything as you can be, and this includes not only the back wall of your listening room, but the heads of other persons who may be listening with you. This is easily demonstrated. Have a friend or loved one sit next to you and listen critically to some music you know well. Now have that person leave the room. The sound will always get better (unless something else is very wrong). I have done this experiment many, many times and it only comes out one way: fewer near reflections, better sound.
This is why we have three pair of Hallographs in our listening room. They help control room reflections. Reflections are the main cause of bad sound in most listening rooms. The louder you play your stereo, the worse the reflections get and the more they screw up the sound.
We like to play our stereo very loud — much of the music we love demands it — and we simply could not turn up the volume the way we do without effective room treatments. Your first pair of Hallographs, even just “roughed in”, not tuned precisely the way they can be, will immediately allow you to play your stereo louder than you could before you installed them. (Since the first pair reflect the sound waves directly back to the listener, Hallographs do actually increase the sound level at the listening position, adding energy and dynamics.
This is a good thing. It’s a clear sign they work.
Sitting close to the speakers eliminates much of the effect of room reflections. So does wearing headphones. I have never liked either approach to listening; both seem very unnatural to me. And sitting too close is a bad idea from my experience. Now, I can only speak for the sound of large dynamic multi-driver speakers, since those are the only kinds of speakers I’ve owned for the last thirty-odd years.
When you have multiple drivers there is a precise distance and height where the drivers blend correctly, or to be more precise, more correctly than any other distance and height. Finding the correct height and distance one should sit from one’s speakers may sound easy, but in fact it is very tricky. It took scores of hours of intense listening over the course of months to figure both out in my listening room.
One thing that made it more difficult is the Hallographs themselves. You can tune them to achieve just the right sound, but when you move your listening position, you must retune them for that position. With six units that obviously became a complicated job. But progress was obvious from the start, so it was just a matter of keeping at it, playing as much challenging music as we could and testing testing testing.
Since we play all kinds of records, all day, practically every day as part of regular shootout regimen, this was much easier for us to do than it would be for most audiophiles. But as I have told many in this hobby over the years, if you don’t do the work the only person who doesn’t get to hear better sound is you. I can come home to my good sounding stereo — I’ve done the work — but you’re stuck listening to all the problems you haven’t solved, right?
Learning How to Listen
There’s no problem with an untweaked stereo or an untreated room as long as you don’t mind mediocre sound. If you actually want good sound, you have to learn how to tweak your stereo and you have to learn how to treat your room. Neither one can be ignored. You have to learn how to do both.
And doing both is what teaches you how to listen, which is a skill that’s very hard to acquire any other way. This explains why so many audiophiles have such poor listening skills. They simply never developed them because they never needed them.
Think about it: Listening to music for enjoyment requires the exercise of no skills whatsoever.
Such is obviously not the case with tweaking. Tweaking your system requires that you listen carefully and critically in order to make the fine judgments that are essential to making progress. Progress in audio from tweaking often occurs in small, almost imperceptible increments.
Being so subtle, these changes force you as a listener to concentrate, to focus your attention, to bring to bear all your critical listening skills.
Naturally, these skills, like any skills, having simply been exercised, start to improve, and continue to improve as you continue to exercise them.
Everybody knows that practicing and challenging yourself will make you better at whatever you are trying to do. But where have you ever seen those concepts applied to bettering your own audio skills (other than on our website and blog)? Just how would you go about challenging yourself as an audiophile?
Tweaking and experimenting with room treatments is one sure way.
Playing ten copies of the same album back to back and making notes about the sound of each side is another.
Adjusting the turntable sixty six different ways and seeing what the effect is on scores of different records works too.
All these things taught me a lot. No amount of reading or advice was remotely as helpful as just getting down and messing around with anything and everything in my listening room. As Van Morrison said: “No guru, no method, no teacher.”
Back to Mapleshade
And having done all that work, with the many stereos I’ve owned over the years as well as those of my friends, I can tell you categorically that the advice quoted above from the Mapleshade catalog is very, very bad advice.
Much of the advice in their catalog I found eminently sensible. If I had more time I would talk about some of it, but we have to spend our days playing and writing about records, not some company’s catalog, so that will probably never come to pass.
I will say this though: there is some real nutty stereo advice in there, so take whatever you read with a sizable grain of salt.
