hi all. after mulling over hours of posts, i still had to ask... i can pick up the svs pb12-nsd for a little over $500 b stock. this is the two 12" version, right? to me, this seems like an absolute steal! it is either this or a klipsch rsw-15 for 1k, or possibly a svs pb13 ultra. i just got rid of a klipsch rw12d that was fair for a sub of that size. i'm looking for some feedback before i pull the hair trigger that is burning a hole in my pocket!! thanks!
