That sounds about right. There is no way I'd omit the HP woofers. Not even a second thought there.

I'm not a tall guy...but...

I just read that the M-100's have a few benefits over the m80 in terms of clarity, imaging, power and bass.

I think of the m80 as a cohesive 2 channel speaker that I would want a sub, then start drooling that the M100 have that extra muscle and allow for uncompressed dynamics.....

10 Goto axiom
Rem m80
20 Seek M80v4 HP
Rem M100
30 Then goto M100
40 If M100>than m80 $500 then goto M100 else M80
50 Goto 10

Great Speakers start with great engineers.
