I'm looking at one of these. http://hometheaters.ecrater.com/p/731765/rs-23000-boston-acoustics-xb4-10-400-watts It's in mint condition and works well. My plan is to replace the "sub" that came with a cheap HTIB in the bedroom. Any idea on what its worth. $200 maybe? My apologies, I thought I was posting in the sub thread.
