On an off topic question Adam, how do you like your PC Ultra-13? I'm looking at getting one very soon...
Love it. Absolutely love it. Great punch, great control, and plenty of power. I had wanted something for years that could do subsonic bass, and this sure can.
For reference, I went from a B&W ASW1000 (12" woofer, amp is something like 150W, -3db at 25Hz) to the PC-Ultra. So, I'm not comparing it to some multi-thousand dollar sub. However, it still has me smiling when I turn the movies up ten months after I got it, and I think that says something.
I think that you will be very pleased!
