Welcome Van. I just put my new Onkyo 3007 through it’s paces with my M80s. First I played my 7.1 system 3xM80s up front for half an hour at 100dB from 11 feet away. Then played it another hour and a half with just the L/R M80s also at 100dB at 11 feet. I finally got the protection circuit to kick in five minutes after bumping it up to 105dB. This was playing GOA Trance and other music with a heavy rapid bass beat. So I think your Onkyo could handle the M80s unless you want it insanely loud.
