Was away for a few days, but hadn't expected more answers. Besides more answers I got excellent information. Yeah I am convinced that the M80s will work great and going to get those speakers and the 150 Center. I am separately complaining to Pioneer since the receiver is THX Ultra certified it should be able to handle down to 3.2ohm.... either way I am comfortable with my purchase of the speakers.

My HT is going up over the next 4 weeks so will order the speakers shortly. Thanks all for the advice and thoughts!
