Question room query/ acoustic panels

Hi All,

I've been playing with my main stereo speaker project, and have found that in my room I have to toe in each speaker by a different angle to get the 'centre' image ,well, central

I believe this is due to having a chimney breast down one side , which causes reflections on the left hand speaker. I've attatched -another badly drawn- pic showing the basic layout. My main speaks are stereo sub cabs with small 'mains' sitting on top of them.

My question - would making some sort of damping panel approx 2' wide by 4' high for the 'mirror point' on each sidewall damp the reflections enough to 'solve' the different toe in thing ? or at least improve on imaging ? My room is fairly damped already, but you can just about get an echo clapping in the middle of it.

The panel would be a frame with fibreglass stuffing, using BAF on the top with acoustically transparent grill material as a final skin.

They couldn't hurt and they're pretty cheap to make. The real answer is rearranging the room (see SAF thread).

Keith Kidder has/had some very nice instructions on his web site on making the panels in a cheap and easy way.

Cheers Sy,

I can't really change the layout - I missed putting 2 doors on the drawing, one on the top wall between the chimney breast and the couch, and one on the bottom wall opposite the chimney breast. Also got a 6' screen in front of the subs, and need the length of the room for the projectors throw. The room is 20' x 10' btw.

I'll start getting some materials ready for the weekend.
I believe it was Keiths site that promted my Q..btw (and Jon Risch's)
