My living room is 14x26x8 (carpeted). My HT is at one end with the wall unit about 11 ft from the seating area. I have 2 B&W 601's in front and 2 more in the rear, with a LCR600 center. Currently my sub (Sound Dynamics THS-10) is on the front wall, but i will need to move it with the new wall unit. I will be moving it (the new SVS) to the corner between the couch and loveseat. My biggest problem is size. Ideally I would like to put a PB12-NSD in that spot, but the wife freaked when I showed her the size. My only other 2 choices are a 25-31pci+ or SB12+ (which she is in favor of). Both are about the same price. She is not really happy about the cyllinder. Do you think the SB12+ will work in this size room? Receiver is a Pioneer Elite VSX54-TX (110x7). BTW, this is used for 100% HT and gaming. Thanks for your input.
