The m80s state they are 4ohm while most receivers run 6-8ohm is that a problem? This integra dtr-20.3 is 8ohm?

I am buying this in pieces right now the receiver and towers then the center and surrounds later.


I certainly want the m80s aslong as that integra receiver will handle them and not cause any problems. Can get the receiver at a disount price of $650 brand new in the box.
