I have very deep carpet plus thick padding and I’m considering buying one. I can’t find a picture of the feet on the PB12. I didn’t know if the feet would just hang in the carpet fibers. My large listening area (23'Lx18W'x14H') is above an, almost as large, two-car garage. I guess I just like the idea of spikes going through the carpet and contacting the sub-floor with my sub. I added spikes to my Velo CHT-12 and it did improve the impact response slightly. Anyone ever added spikes to this or a similar unit? Any other feedback would also be appreciated.
