I've been active on this board lately, in the quest for the ultimate rig. Anyway, does speaker sensitivity make much difference when pairing up cabs? For instance, what are the consequences of matching up a cab with 99db 1W 1M to a cab rated at 103db 1W 1M? Or a more drastic diffrence like 90db to 103db? Thanks to everyone who has helped me with my questions. I have been rethinking (obsessing over) my rig the last month and the input I received was great.
