Though I have not proposed it yet, I plan to see if I will get an objection from the wife on getting the Cylinder series instead of the Box. If I get a "NO" then my decision is made for me. What I'm looking at is the following: 4300 Cubic foot room with 2 small doorways(one can be closed). Listen to movies at 0 but when the wife watches a movie we turn it down to -15 to -20. Action movies primarily for me. Sub in the front left corner about 12 feet away from the listening spot. From looking at the Cylinder series parts and looking at my budget I'm looking at the following: Pb2+ Dual 25-31cs+ CS Ultra with S1000 amp This will be it for a while otherwise if I could buy one now and then buy one later to add to it I would go the PC Ultra probably. Then again maybe the Pb2+ is overkill as it is.. Any thoughts? I've emailed SVS but I like to hear from others. I assume floor space will be roughly the same.
