[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. (more…)
