To me; the ultimate would be a pair of self powered M80s(or even bookshelves)with digital amps matched to the electro/mechanical characteristics of the drivers/cabinets, and the ability of each individual listener to tailor his or her listening preferences to either warmer/cooler, as well as intense/subdued character, as the listening material and room parameters required.

Hey, with intellegent control over all those individual drivers, plus the port lengths....no different than mapping fuel injection!!

I 'spect that it's gonna happen soon; just be nice if Axiom got there first!!
