Yeah, in my living room, the M100s are way over the top when it comes to bass. My living room provides a nice boost that gets the M50s to play well right down to 30Hz. The room is good for the M2s also. The M50s, M2s and A-LFRs are the only Axioms that don't need bass EQ in my living room. The A-LFRs are better than perfect in that room as far as bass is concerned.
