Is a down-firing sub into carpet OK?


I have a down-firing sub and it is firing right into carpet? Is this ok or should I get something for the sub to sit on like a slab of marble?

Contrary to popular belief, downfiring subs are fine on carpet. Bass waves are so long, the thin carpet (relative) is not even a factor to bass response. Infact, firing into a carpet (port as well), if anything, would elimiate some high frequency distortion if at all present. Downfiring designs have this advantage. Still, your main concern with any bass woofer is location and coupling to the room, in relation to where your ears are located.
Absolutely! It's a highly effective way to scare the carpet critters out of the house.
If anything, I'd put the slab of marble "on top" of the sub! That added weight should make the response stronger, tighter, and more solid...if anything.
