Y'know that's a great idea. Although I've not got an awful lot of experience with MS-12s, it sure would suit the Mark IV very well.
Seeing as the IV came with C90, are we going to see people retrofitting Mark V amps (when/if they come out) with MS-12/EV speakers?
It'd sure be a good time for Boogie to jump back on the MS-12/EV bandwagon. Good point!
