Hi all, me and my girl were shopping at crate and barrel the other day and I picked up a couple of these
wood wall art thingys (just because they looked cool) and I was going to place them on each side of my TV for decoration. In the mean time, I stuck them on the floor behind my speakers until I could get them hung up on the walls and until then it didn't dawn on me that these would be pretty good diffusers. I got to say I heard a difference right away and I'm one of those guys who doesn't hear a lot with cables, etc., but this really stood out to me as a difference in my room.
They're not as technically advanced as dedicated designs, but they do have some diffusing properties, are fairly cheap and good sized, can be mounted either horizontal or vertical and are pretty cool looking in a retro sort of mid century modern way. Anyways, they are on clearance at the Crate and Barrel Outlet.
$50 a panel and they are 42" x 14" and made out of recycled wood. I like them so much I'm going to pick up a couple more for my back walls.
