I am new to the forum and am in need of some advise. I have been looking at subs for several months now and after reading the reviews about SVS I have decided to buy one. I have received some great advise from Tom V. but would also like to hear from those that have similar room setups. My listening area is 20x15x(8-18). It opens on one side to a kitchen that is also 20x15x8. Additionally, at the high end of the vaulted ceiling there is an opening to a loft. My receiver is a SONY STR-GX909ES with Dolby Pro-Logic. The speakers are Def Tech BP-10s and Def Tech center/rear speakers. I really only want one sub so my questions are: 1) Can I use the 20-39CS(+) effectively with my Pro-Logic receiver or should I consider the 20-39PC? 2) If I went with the 20-39PC would it provide enough bass in my room? Or maybe I should wait for the 20-39PC+! Thanks for the help!
