Downward facing subwoofer on carpet, bad idea?

IMHO, most all sub's are placed on carpeted floors, and most are downward firing. You don't lose low frequencies reflecting off carpet - only high frequencies - so there should be no problem at all. My Rel sub is on carpet and fires down . . . sounds wonderful.

My 2 RELs are also on carpet and work better in my room than my 4 12" each bipolar subs. I use cones under the rubber feet of the subs; may or may not improve sound for you. I checked with Sumiko some time ago about whether carpet was better; the person I talked with said bare floor but the technical person who later emailed me said carpet.

Mo,

It's not a bad idea, but it's not optimum. Place a solid surface, like plywood or a large floor tile, under your sub and compare. More of the sub's output will be reflected into the room by the hard surface verses some of it being absorbed by the carpet and padding.
