RE: Front wall room treatment for dipoles, Maggies, others

Posted by GStew on November 25, 2009 at 21:54:46:
My most sophisticated room treatment (realize this was back in the late 80's) was with homemade tube traps and a pair of highly modified Acoustat 1+1's.

The main traps were 12" diameter 7' tall tubes of 1" polyfoam with foam core board circles top, bottom, and middle. They also had 1/2 covered with plastic (heavy trash bags) to do the absorb/reflect thing the tube traps do.

I had one in each corner behind each speaker, one on the wall directly behind each speaker, one on each sidewall directly beside each speaker, and one at the 1st reflection point on each wall. But then I also had one directly behind each speaker leaning up against it. I would not say these made the biggest difference... it was definitely an ensemble thing, the whole was greater than the sum of the parts. But these made a significant improvement in clarity and detailing and it was very noticable when they were removed.

YMMV
