I set my sub woofer and controls on a rolling cart that houses my rackmount equipment(Bbe Sonic Maximizer,mixer,vocal harmonizer)when I play out. I had thought that the sub woofer had to be on the floor,because that is where they belong.

I found that elevating it say 16 inches does not detract from the sound, especially as strong as that is.

Chuck, that's a good idea.
