Are you happy with the sub now and does it meet your expectations or not? I'm looking at getting one as well, but I want to feel it hit in my chest. I've read a lot of up and down threads about these subs. It's either the EP500 or one of the SVS lines of sub.

Receiver: Yamaha RX-V2200
Main: Axiom m80
CC: Axiom VP150
Surround: Axiom QS8
Sub: SVS PC13-Ultra
