I'm changing my home theatres around a bit. I have:
4 Polk Audio DSW 3000 Micro Pro subwoofers with boxes etc. Perfect Condition approx. 14 months old and $900 each. ***Update, there are 3 left $850 each

and
4 Klipsch SW 115. Perfect Condition with boxes etc and 2 weeks old with about 90 minutes play time $650 each. I got these to fit into the shelving in the theatre, but I went off the framing dimensions and forgot about the drywall, soundboard, and baseboard thickness... 2 inches too big. ***Update $600 each

and
Dynaudio Focus 220 Mark II in black, 2 years old, perfect condition, barely used. $2500
Unfortunately, it's all in Edmonton.
