shadyJ - Thanks much for the extensive break down. Having the prime towers and center already, their subs were the first place I looked. Having learned many lessons over the years trading quantity for cost, I have come to the point where I try hard to spend what I can for something that I'll have a very difficult time finding reasonable excused to upgrade from a few years down the line. That was my goal here; thinking that a single PB-3000 now, not having the money for 2, or even really the room, would provide me the best initial return and also room to grow if I could end up with the money and space for a second later. I was also hoping the experience of going from zero subs to 1 would give me far more happiness than going from 1 to 2 would. I'm thinking that a single PB-3000 would make me quite happy for a long period of time. Not sure if going from zero to 2, and having no idea what difference a single one would have, is the best money to value proposition. Though, admittedly, with the 45 day trial, I'd need to be on guard from letting myself get talked into trialing 2 with the thought I could just send one back hahaha
