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.

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.
50% of the sound you hear in a well designed listening room is indirect--bouncing off other surfaces.

It certainly is.

This is why it is so important to select speakers with an even power response and good horizontal dispersion (with similar off axis response over the entire frequency range). This way your room is loaded correctly and the reverberant sound field remains balanced along with the primary signal directed at your ears.

A speaker with uneven power response or very narrow dispersion will have a very limted sweetspot and will be highly sensitive to placement => it will likely only sound good in one spot with one listening position. A good speaker should mean that it sounds balanced around the entire room.

Room treatments will still be essential but much easier to employ if the speaker has an even power response, as the main issues will be bass trapping and some reduction in nearby first reflections (anything that beams sound at the listening position like a wall too close to the listener or speaker)
Good point. Room treatments are still one of the greatest untapped resources and many folks with high-end gear still refuse to see them as one of the most critical components in the system synergy. For me personally, acoustic treatments have taken my Hifi to a whole new level.

Happy (acoustic treated) Listening!
WHich is more effective for the ceilng, RPG Skylines or Hemmifusors? And what is the difference between Skyline and Skyline LP? The Skylines reminds me of Jor-El's sanctuary albeit an inverted one minus the crystals. Noticed a few members here with these on the ceiling.
