Here's my question. I currently have a pair of SVS 20/39 CS+ subs (with the Samson 1000), and am thinking of moving to a pair of Ultras. I already have a PB2+ as my LFE sub, so the Ultras will perform "stereo" sub duties, as well as handle all the bass (except LFE) redirected from my M&K S-150's. Given the fact that I will probably add room correction to my Lex MC-12 soon, does it matter one way or another if I go with the CS or PC version of the Ultras? Are they basically going to perform the same? I really like the idea of not having to plug the sub in, since I ran my speaker wire through the wall - and it comes out exactly where I need to place the sub. The outlet is about three feet down the wall. Not a big deal, but I'll see the cord! Let me know your thoughts! I'm dying to get that TV-12 driver!
