Re: Acoustics tips and help, please


Ok, finished all the materials I have so far. I'd like some input as to the most effective use of the stuff I have. So I'll list it all;

5 pcs 1 1/4" 2'x4'
6 pcs 4" 2'x4'
4 pcs 3'4" corner chunks, 2' face
2 pcs 2'6" corner chunks, 2' face

Currently I have the 4 larger corner chunks on the floor in each corner.
In the front corners I have one 4" panel straddlign the corner on top of the chunks, so they fill floor to ceiling.
In the rear corners (where I have my sonotubes) I have the smaller chunks stacked on top of the larger chunks, with one 4" panel straddling the corner in front of the smaller panel (if that made any sense).

One 4" panel in the first reflection point from the left speaker. This covers the reflection from the center as well, on the left wall.
Three 1 1/4" panels stacked in front of each other, making one 3 3/4" panel on the right wall in the first reflection from the right speaker. I have a door here that prevent me from killing the center channel reflection on the right wall. I'll live.

Two 4" panels upright against the front wall behind the main speakers, and two 1 1/4" panels next to those, toward the center, and the last 1 1/4" panel horizontal behind the center speaker. So my front wall is covered up to 4' high with at least 1 1/4" and up to 4" (some of the front wall panels overlap)

I plan to get another case of three 4" panels and mount them in the ceiling to kill the 1st reflection from the left, center and right speakers.

The room sounds awesome as it is now. Going floor to ceiling really helped, as opposed to the 6' stacks I had before. Ceiling height is just over 7', but covering that last foot really helped.

I feel maybe having the small chunks behind the 4" panels is overkill and could be put to better use, but then the subs are right against those corners and I figure they can use all the absorbtion they can get back there.

Any views or suggestions as to what I should do? I enjoy the room as it is now, but things can only get better, right?
