Room Treatment: Whatcha Got?

Roughly 15 - 20K worth of treatment. Soffit mounting of main monitors and rear wall behind the listener treatments were the most costly probably because I tried to get an aesthetic result. It may not have been enough as I still use a PEQ to tame the subwoofer for room modes and I also have four large GIK corner tri-traps.

I have a bunch of corner tunes, one in each corner and these really do work and you can hear the difference/it is better with them.. this is one tweek that has worked for me.

I have ASC 1/4 rounds in the corners from floor to ceiling behind the speakers, ASC tube traps on rear wall and side walls behind speakers. An ASC 1/4 round in rear corner behind listening futon, other rear corner is open via a door. RPG studio foam panels at first reflection points from floor to upper mid level. Room has wall to wall carpeting. Speakers are set up semi diagonally in the room.

Michael Greens corner traps in all 4 ceiling corners and MG corner strips midway along the wall/ceiling.
ASC 1/4 rounds are augmented by Teknasonics vibration absorbers and the whole room is treated with Golden Sound Acoustic discs.

The room was an acoustic nightmare before treatment but is now neutral from top to bottom while not being completely dead.

I purchased an Auralex kit which is versatile and performs well but has low WAF. Also have a couple of DIY panels which work very well. Heavy drapes cover the window behind the equipment.
If your room is dedicated to audio, room treatments are essential. I know because I hooked up my system in the room with bare walls all around. Then went to work with the treatments. What a difference.
