No, I those speakers are just about 91db maximum sensitivity. Regardless, the F-1 and the Final Music 6 amplifier are totally different in design. I am wild to guess, but it might be true that the Final Music 6 will be a great match for those speakers and drivers, if only drawback would be that they will require change of batteries more often....Mine with the Fostex 208 Sigma can go for a good 3 months, in your case, I think it will be about 1-2 months at most, but of course, it depends in what sort of listening habits you have. I have a pair of F200A seating in boxes and plan to get a pair of MTLM? Cabinets for them from Bob Brines and pair them with my newly acquired First Sound Paramount Hotrod MKII, the Final Music 6 and or the Assemblage 300B amplifier I have. The bottom will be relieved of duties to an Infinity Intermezzo sub. What sort of amp are you using with your cabs now?
