I have wall to wall carpet in my ‘Music Room’… I bought a pair of ZU, DW that have a vent hole/slot in the bottom of the cabinet. They sounded nice but had way to much bass. At the advice of a friend I ordered a pair of ‘Butcher Blocks’ to fit the size of the speaker cabinets. Once I put those speakers on top of the wood blocks, it sounded WAY better! It took away the muddy too much bass sound. The bass became much more ‘Punchy’ instead of ’Boomy’…
