Welcome Boomzilla,

Re your question about the bass difference between M80s and M100s or LFR1100s, it is really more about the M100s and LFR1100s being more linear in the entire bass region below 100Hz than it is about a few HZ at the very bottom. There is also the fact that the M100s and LFR1100s with the power pack option that is now available are capable of much greater overall SPL output in the bass before any compression occurs.
