Hiya, I've finally convinced myself its time to take the SVS plunge and get me a new subwoofer!!! I'm torn between two models and looking for some advice. Little info on my room… This unfortunately isn’t the ideal HT room but has to do for the time being. Our home is a "great room ranch" design and so is fairly open Its 14.5x21.5ft with an 8ft going to 11.5ft vaulted ceiling. There is a large 9ft opening behind the viewing area into another room. The subs I'm considering are the 20-39PCi and the CS+ with the Samson amp combo. I know which is the "better" option but what I am wondering is, if I’m going to get the kind of increased response from the CS+ over the PCi that I’m looking for. At the moment, I'm leaning towards the PCi unit. The primary reasons for selecting the PCi right now are convenience of the built in amp and also for price reasons. I plan on one day setting up a HT room and like the idea that I could add an additional CS+ to the Samson amp later on but this is only a side thought. So what are your recommendations? I don’t want to make another sub mistake as I did in the past with my current sub (a very disappointing Yamaha sw160 ) Do you think that the CS+ would give enough "bonus" to warrant the $350 premium?
