I need to get some speakers for a spare bedroom (average size) that we use as an exercise room that has a TV and DVD player. I am debating wether or not to move the Boston Acoustic speakers from my HT to this room and get new speakers for my HT or to just buy something for the spare room. My HT right now is as follows.

Boston Acoustic SubStat 6 II front
Boston Acoustic Center Channel
Boston Acoustic C6 bookshelf speakers rear
Outlaw LFM-1 sub
Definitive Technologies BP 10B towers (rear surround used mostly for music)
Dennon 2803 Receiver
Pannesonic 53" HDTV
Sony DVD player
Kennwood 5 disc CD changer
JVC stereo VCR


Any suggestions?
