Square room Soundstage??

I too have a changeling listening room. A heavily treated 12x13x10. GIK Acoustics has been a useful resource in getting things sorted out for not a lot of coin. For my situation I went with their Soffit traps stacked lengthwise in the front corners, 242 style absorbsion centered between the traps on the front wall, three Monster Bass traps side by side on the back wall, and two QRD Diffusers at the first reflection points. All told it reduced the bass nulls, improved soundstage depth an width and provided greater midrange clairity.

Vapor,

Thanks for the detailed response. I am going to start pricing things out. It is very helpful informtaion on placement.

Yes, treatment will help. I get excellent imaging in my 12x12x8 room. Sent the dimensions to GIK, treated 1st and 2nd reflection points ( Including ceiling ) and it still took 3 years to finalize speaker placement.
