Just a thought on the sub, look at the 20-39 PC+, compared to the PCI. I have NOT heard the PCI, so I can't really say. But if you look at the 12" driver on the plus, you'll see qiute a difference. And the 525 watt amp, compared to 320. maybe not a big deal depending on your intentions. It's 225.00 more. The way SVS explained it to me was there was a "considerable" difference in the jump from PCI to PC+, and while still a jump up to the ultra from the PC+, it was not near as significant, but again a better (their best) driver in the ultra, just a thought. Same size and physical characteristics regardless.
