I see where your going ... after rereading you're post on parts ... I'll give it to you ...

If the LFRs share the same x-over and the M60/M80/M100 have different x-overs then there is a high likelihood the the LFR1100 uses the M100 x-over.

Which mean that if the structural changes doesn't significantly effect the sound (which the DSP corrects) then Rodney's statement of having an M100 equivalent is correct. smile I personally would still ask Axiom.
