Our main reason for bringing out the High Power versions is a recent resurgence in 2-channel systems. ... Some of these systems utilize large power amps with no subwoofer
Huh... time to bring back the M40 in High Power !!
I always liked the M40 for a 2-channel music system but had to agree it didn't make much sense in a home theater system.
Someone mentioned before (forget who) that the high powered version of the bass drivers are designed for dedicated woofer applications in a speaker and not as a midrange/woofer like what you see in the standard 6.5" drive unit used in the M3.
Or not. Oh well
