Thanks for the input. Just got back from there. They really are fantastic sounding speakers. First one's I've ever heard except maybe drooling over them in a stereo shop during my teen years. He replaced the woofers about 8 years ago but not the crossovers. They're OEM replacements but not the upgraded models. I really liked the tonal range, very good on the low end. What kept me from pulling the trigger was the condition of the cabs and covers. 4 out of 10 at best. One of the tops was water damaged with a plant or something with veneer also gone on one of the corners. One of the covers was cobbled together and missing the badge. I offered him $150 and he declined. I was waffling, thinking of coughing up the extra $50 cuz they sounded THAT good and he shooed me out the door. I get the feeling he's not sure he even wants to sell. This may not be over he lives 5 mins away and we have each others numbers.
Great way to resurrect an old thread like this. Good inspiration too, I’ve got a pair of C2’s that have been sitting in the garage awaiting attention for years. I’ve been determined to do the foam right, reversed like you did. Congrats on such a nice workJust hooked up my restored C2 speakers to my 30 wpc MAC 1500.
Easily pushes them to enough sound in my 12x16 room.
I used Parts Express 10” foam and installed it inverted like it was originally designed to be. The sound wave terminates better, according to my old Ohm paperwork.
I used a 30hz tone to center the VC. The gap is tight.

Oddly enough, I didn't have to change the caps in my C2s.
i have learned not to "fix" something that's not broken!
