I have a sub that an underinformed tech blew by bridging my stereo amp and not compensating with the gains. Anyway, the cone is carbon fiber epoxy and the surround is "mystery-rubber". I think the speaker is fine except for the separated surround...went from "good" to "slap/farty" immediately, and after we pulled the sub from the cab, I saw the surround/cone separation. $350 for a replacement is not in my immediate future. I've read a bunch of sites about fixing surrounds, but most of them talk about paper or fiber cones, not fiber/epoxy. Is there anything special about fiber/epoxy cone and rubber surround repair or do I treat it the same as a paper cone? BTW, I own a 5-string Fender P-Bass, but I'm a guitarist...though I do favor the E and A string! My neighbor owns a Veillette (Woodstock, NY) baritone nylon string piezo-electric guitar that he refuses to sell to me...half way between bass and guitar is where I think my soul resides. Maybe I should up my offer to him...$2000 for it. Hell, I can't afford $350 for a speaker.
