is is 40 feet thick? bass wavelengths are very long and tend not to be be affected by small obstacles hence why down firing even works (the baffle is a small obstacle) Try that with a tweeter and you'll lose your high's.
It's not really going to matter. Probably less than 1% between the two. Like Kyle said, very long wavelength means they can curve around objects without any issues. 3/4'' long strands of carpet won't even be a factor really. If anything carpet will absorb any higher frequency noise (pops or clicks) that the sub might produce.
