Just did a quick set up and testing of the M80s on the rear channel, so far its sounding great. The Outlaw 770 handles the four M80s with no problems, still have some tweaking and long wire runs for the rears to complete. Will try and find time soon and post pictures on a web page of the new system. If one has the room and budget, using M80's for front/rear, VP150 center, QS8's for surround, and the EP600, is a great sounding system in my opinion. Will try to get some pics soon, thanks for all the helpfull info on this forum.
