At first I wasn't sure about it. My basement is carpet on concrete, and I put the sub without feet in a corner (I have no flexibility in placement unfortunately). It rattled everything like crazy! Next I put it on its rubber feet, and this seemed to help the rattling. The accuracy was fantastic, but I was missing tactile response. Eventually I tried the sub without feet again, but with one difference: I pointed the driver away from the wall and out into the room. That did the trick! The rattling went away, and the TR improved.
I recently also upgraded my mains from Sierra-2 to Sierra-2EX. These have what I perceive as improved punch or slam (with only a touch of warmth over neutral), and the whole system really sounds phenomenal together.
This setup uses XT32 room correction, but pretty sure I would benefit from a second sub and/or some DSP correction for the sub specifically. It's a bit of work though, and I'm just really enjoying the setup as it is right now. No regrets!
