I use a SVS Ultra 12/2 sub. They are amazing! They are still the best ultra sub svs has made IMO. I purchased one before they went to the ultra 13. Ron(at svs) told me that the new 13 ultra would beat a single ultra 12, but wont be able to beat the 12/2 until it is released in a dual version also. That never happened. I am glad ron talked me into the svsultra 12/2. I soon later bought a second because I was so blown away compared to other subs I owned(at one time used 3 subs at once-the ML descent, servo 15, and hgs-18). I actually sold the 2nd ultra 12/2 after a few months because it was just too much bass in the room(prob should have went with two single cabinets really to smooth bass response in rooms suckout areas/etc). You can't imagine what the 12/2 ultra is capable of. It's almost too powerful, because it can be tough to smooth it out from being boomy/etc in a smaller room because its just so powerful.
If you can score this for under $1200, I'd grab it because I know what it's capable of. For under $1000 IMO it's a steal(as long as its in good working order). Nothing else will come close forthe price. My only negative about this sub is it looks like a coffin in the room. The new ultra 13's look a lot better
