Does anyone make a 1'x1' or a 2'x3' diffusor?

Tim,

Thanks! Unfortunately, all they have are absorption panels, they don't make diffusors.

Well, hardware stores sell things called "saws"...

Check with GIK Acoustics and they do custom sizes on their items.

I have plans for diffusion panels we built as a acoustic fix for a youth performance school. The room was a huge semi-circle the panels were built on a jig to conform to the room shape. I think we built up 53 panels some 10 ft tall and almost 8 ft. wide. We used common everyday materials..you could add some long hair sheep's wool between the one inch wooden dowels to comb out some reflective frequency bounce.These panels could be built in any size.
