Tough call. I'm leaning right now toward the VP100 just below the TV. I can't speak as to the loss in sound (I've never heard the VP100)- but Axiom says the main difference is the power level the speaker can handle. By the specs the VP100 should have no problem keeping up with the M22 mains (both rated at 200 watts), and should be fine for seating 8 feet away.

Hopefully you'll get some additional opinions- and you could call Axiom and refer them to this thread for their advice as well.

Good luck,
