I had the same problem, since I wanted to mount the unit in the carpeted den
on a concrete slab.
I drilled three1/4 inch holes through the carpet, making sure that I did not
catch the fibers in the drill.  I then injected a little epoxy into the
holes and inserted 1/4 inch screws.  Onto this I mounted a plate with nuts
above and below.  It seems to be a very stable platform. I hope that the
screws will be removable by use of a wrench when necessary (don't use too
much epoxy-perhaps I should have greased the screws first).
