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!
How did the tactile response of the F18 compare with what you had on the LV12R? Many over on the Rythmik AVS thread seem to say that one of the benefits of the ported subs is that they can give more tactile response than the sealed subs. Though you have a huge difference in output capabilities going from the LV12R to the F18. The F18 has more output likely at every frequency in comparison.
