The Room


Most often we hear folks saying the treble's too etched or sharp, sound is too bright and forward and piercing the ears, sound is 2-dimensional and flat, soundstage is lacking, not enough dynamics, bass is too loose or boomy etc. and often pass down comments of the equipment based on their listening experience. I wonder how many folks have a proper listening environment to pass down their judgements on the sound signature of the gears that are being reviewed or listened to. I am still in the learning process and have found that room treatments can have a huge impact on the sound, although in most cases results will vary with different rooms and environments.

I believe that any hard or bright-sounding components(perennial favourites are B&W speakers or Krell amps) when put together in an overdamped room will produce a sound that's dull to the point of being dead. Whenever I read comments on B&W's being harsh-sounding speakers, I don't know if they are being listened in a crappy room with bad acoustics or it's just the haters. Even with very minimal absorption on the sides and diffusion on the back, there is no issue with brightness at all. More absorption would kill off the high frequencies and make it too dull.

Just wanted to share my observations and experience. In my opinion, any particular description of any component's sound, taking individual listening tastes and preferences out of the context may not be too accurate based on the room layout and acoustics itself.

And just to point out, I am in no way associated with any room treatment manufacturers. Just a curious learner and currently still trying out different treatments to improve the acoustics in my small room. Have just got rid of the pyramid foams on my side walls as I figured out I can't live with the looks of it.

By the same token, one can spend a large some of money on the room, and if poorly designed, end up with a poor sounding or even unlistenable room. Then you're in the same position of essentially chasing the right gear to make up for the bad room. Hostage negotiations with a bad room can get a bit costly, not to mention frustrating. So if you're going to do it yourself, or hire someone, make sure it is done right. Up front. Primum non nocere. And since I'm in a Latin mood, caveat emptor.
Ryder:

The ceiling is actually quite important. There was a group of Dutch researchers that showed the ceiling had the single biggest effect on sound quality (this was for a typical rectangular room). It makes sense because the ceiling is almost always the largest bare flat surface. Dealing with 1st refection points and using either pre-fab (RPG skylines or other) or self made diffusion for the ceiling can have a huge effect.
Rives.

And the elimination of 90 degree angles is the first place to expend funds. Tom
I would like to try something for the ceiling. Anyone know of any easy methods for application? Don't want to break my back you know.
90 angles aren't the problem. People treat corners because they are the highest pressure zones, and thus trapping in the corners becomes the most effect--it deals with 2 and often 3 of your axial room modes. We often use soffits with single layer sheetrock. 90 degree sections are still there, but you have disrupted the area of the highest pressure and distributed the pressure and thus reduced the peaks and lowered the Q factor for the peaks. That's probably what you meant--but I just wanted to clarify it a little further.

As to the ceiling, RPG skylines and hemifusors are both excellent products and easy to mount. The downside is that depending on how much surface area you are covering it can get expensive.
