I recently purchased (4) M60's and the VP150 to put together a home theater system. My question is merely out of curiosity. Ian has said the M80 has more dynamics than the M60 so I was wondering how the (4) M60's would compare dynamically, to the (2) M80 and (2) QS-8 system you have in the Epic 80 HT system. Just wondered what the advantages and disadvantges each system would have and Ian's overall thoughts on the subject.
