I have towers for surrounds, and I think I want to try to raise them 4 - 8 inches off of the floor. I need something like 12" by 18" (by 4-8"). A trip to the local hardware store to just make something would work (2x4's and plywood, or some bricks with just some plywood over the top), but I was curious if anyone else knew of options. I know about Sound Anchors, any others? Thanks!
