Short version; CF-4 needs tweeter diaphragm or driver replaced.
My usual snails pace, over the last three days I finally shuffled around our living room and parked my Forte's and hooked up the set of Epic CF-4 speakers I bought about a year ago.
These are freaking heavy speakers, 108 lbs each, much grunting and groaning, finally hit play and ..... one tweeter isn't working. OTOH seems like the other 5 drivers are fine, but a bit more checking is on the table before I do anything. Not fair to compare with one bad tweeter, but the sound is VERY different from my Forte speakers.
Anybody has a spare tweeter driver that is known good, I will either buy or send mine off to Crites for repair. I may do that regardless, but I am also considering use of EV DH1506. Kicking myself on the EV as there was a pair local to me for $75 and I was too busy to go buy them. I always like to get a good item back to proper stock operation condition before making any changes, but I do have the usual list of mods at the back of my mind.
These are not the first version, info I think is in my sig. Ultimately they will be used with a subwoofer with the mains high passed no lower than 60 hz, so the ports may not matter.
