Hello-
Fellow Klipschie here.
I think your amps are a fine match for the KLFs, so don't sweat that part at all. [edit: oops, I see that that is a stereo amp...I think there are many options, but I would recommend avoiding the Emotiva amps, as their super high gain is often not the friendliest match with super sensitive speakers.]
You may want to add bracing or other reinforcement to the cabs. Contact Klipsch for brand new, better performing compression drivers, and then Bob Crites (
About Us | Critesspeakers.com) as he is the crossover guru for the old Klipsch (although there are other privateers that do the same thing, Bob's probably done more than anyone else).
