I have recently decided to purchase an SVS Subwoofer, however, am not sure which one to get! I will be mating it with a Denon 3802 receiver and matched Klipsch Reference Series speakers (R*-3II models). I cannot spend any more than 1000 but would preferably like to pay less if possible. (at that price, I would be paying almost the same for my sub as the rest of my speakers! Is that worth it?). Should I be looking at the PCi models or the CS models? Will I need to get a separate amp, and if so, which one? Additionally, is there anything new coming from SVS in the next month or so I should wait for? Thanks for the help!
