Don't know your budget Jimmy, but John, in that price range($600) you will NOT go wrong with the STF-3 (I have the STF-2 is a smaller room (11.5 x 18 x 8), or the SVS PB1-ISD. (Jimmy, also in that price range is the SVS 20-39PCi, but it's a cylinder, and NOT in John's future
). Some here recommend Hsu, some recommend SVS. The truth is, it's a win/win decision.
I always recommend contacting the companies. They are known for excellent customer service, and will NOT try to talk you into something you don't need.
Hsu has a
Product Recommendation and Support Form you can fill out and submit, and they'll get back to you with their recommendations.
I don't believe SVS has a form to fill out, but the have a great
FAQ page, and they recommend
contacting them with your listening habits and room size.
