Whats the best wall properties for home theater.?

Question

I'm putting a home theater in my basement what should I use for wall beside the acoustic panels. drywall, carpet, wood, etc???

Answer 1

I recomend walls that are covered with acoustical tiles for the best sounding room with the least echo.  if you have sheet rock walls, it should be O K, you do need to try different speaker placements, to see what placement works best in your room.  try the placements with your prefered E Q settings.  when you get everything how you want it, then try any fine tuning of your E Q settings, or which settings you want to select, if you have pre programmed settings.  also if your amp/receiver has it, the auto calibrate can save some time.  dry wall is a good choice for basement walls, also do use acoustic panels/tiles.

Answer 2

This is an area that I have had least success with. The two home theatres I have built don't have ideal acoustics (not bad, but could be better despite my attempts to address acoustic issues during design), and I suggest a more specialized forum for authoritative advice (See the 1st and 2nd links)

That said, you really want a mix of reflective and absorptive material otherwise the room will be either too bright (all drywall) or too dull (all tile, drapes, foam panels, etc.).

One guideline I have read is to have about 1/3 of the wall surface be some form of absorptive material (e.g. acoustic tile, foam, drapes), and the floor have a carpet or rug at least near the front of the room.

Bass standing waves can be a problem, but can be tamed with "bass traps" (See 3rd link for ONE approach).

Of course you need to setup your equipment properly and "calibrate" the audio for speaker setup and the room.

Hope this helps.
