That is a speaker design I and many others have asked Axiom to make for many years now, a small(ish) 3 way design. I think this should strong down to 60-70 hz range or at least sound like it is with a minor bump in the FR much like the M3. I have been tempted to modify my M22s to accept the 6.5" driver and make my own crossover but I never could convince myself to potentially ruin my M22's. Looking forward to hearing about this journey.
