My non-dedicated room is about 25x15, with 2 openings. I have had the SVS 20-39 PC+ in my theater since it was introduced, so it has the original driver and 525 watt amp. I very occasionally bottom it out. Right now SVS has the PC12 Plus for $100 off, making it $500 less than the Ultra. Will the Plus be enough of an upgrade, or should I go with the Ultra? I plan to use it crossed over from my mains (PSB Synchronys) at about 50-55Hz.
TIA for any help!
