I know this is crazy late and don't know what decision you made, but I will tell you this. I have 2 PB2ks and added 2 PC12+s to the family tuned in 16Hz mode and I will never
need anything else as far as low-end extension goes. It's absolutely phenomenal and brought together the entire audio experience. We're speechless. So phenomenal in fact, that the wife wants to watch all kinds of movies over again just to experience the newly found expansive and visceral sound. When she heard Deus Ex Machina speak her eyes were larger than I've ever seen them. This quad sub combo was worth every penny spent. Duals? Impressive. Quads? Unreal.
