Another vote for the 160 here.
Was running mine through my receiver for the last couple years totally awesome. Picked up one of the 3 channel ADA1250s on the sale now with it hooked up to the ADA it's totally phenomenal, hits way lower {the wattage rating is just a guide line} as Axiom test the speakers with 2 or 3 times their recommendations

Plus with your M80s the larger center looks and blends so nicely.
