Ok - I get it. And having the C/O set at 80 (I'm not going to be tinkering with the sub much, if at all) is optimal for both HT and Music?

If I switch my Yamaha 1400 to just play the M60s in a stereo setting for music without effects or DSP, will the M60 reproduce sound in the speakers full bandwidth, or will I lose everything below the 80 HZ C/O? In other words, will I have to keep my sub in the loop for everything if the C/O in my amp is set to 80?

And a follow up - if this is so, and I'm not going to be tinkering - should I opt for the M50s or the M22s since the lower end of the M60s won't ever see the light of day?
