I really want to place the sub under my component since that is the only place for it in the media room. Are there any racks out there that can accomodate a subwoofer as well as other components (blu-ray player, cablebox, receiver)? I have been looking around but haven't found anything. Some of the racks that I have found maybe able to hold a 8" sub but I'm kind of worry about vibration.

Check out the Yamaha YST-FSW050 and the YST-FSW150.

Those would fit in any normal equipment rack.

A subwoofer's primary purpose is sound.

Sound is vibration.
