Alan, I noticed this before in your other thread, but didn't comment on the point; but why would you voluntarily discard your best speakers for any of your listening, whether it's movies, music, or music in movies? As Mary indicated, why not use the M60s as mains in all circumstances, with some of the Quintets doing surround duty and possibly letting the M60s also form a "phantom" center?
You're correct about the upper bass hump that many small speakers use to give an impression of better low bass extension. Bass instruments playing in that range sound a bit louder and in addition a low bass note, say 50Hz, will have its 100Hz and 150Hz harmonics boosted, leading to what's sometimes referred to as the "missing fundamental" psychoacoustic phenomenon in which the boosted upper harmonics give the impression that the fundamental frequency is there. My listening and viewing of response graphs indicates that Paradigm uses this technique on their smaller, lower-cost speakers.
