The write-up for the M80's states 2 tweeters, 2-mids, and 2 woofers. The specs state two woofers and two sub-woofers. Does anyone know the crossover freqs for this for all sets of drivers? Do I need a separate powered sub if I get the m80's versus the M60s ?? I love the looks of these speakers and I'm having trouble deciding between these and Aperion's...
