pickintrade, I use to sell the klipsch rw12 or rather I could have but never would if at all possible. The rw12 is a little sort in the pants when it comes to deep bass output. Not always but often enough people would bring them back with their voice coils fryed from trying to get something out of them that was never there to begin with. Klipsch builds great speakers just not great subs. There are several better subs on the market for the same or less money. I strongly urge you to go with something other than the rw12.
