HPM 900 repair question

[Dire McCain]

Finally found some HPM 900s but one of the graphite cones is cracked. It's a clean split and should repair without problem if someone will tell me what type of cement will adhere to the graphite...I tried superglue without success.

Anyone have any experience with this problem? I would appreciate your
help...

Thanks

I would run a thin layer of epoxy or Goop on the backside of the cone.
Good Luck

Here's a post about a pair of Pioneer S1010 speakers.

The S1010 use the same type of material as the HPM 900

Send a PM to Kelly (kfa888) as to how he did the repair in detail if need be.

Kelly here. I just ran a small bead of two part epoxy down the back side of the crack. Been holding well for many months. It stuck VERY well, as in you would brake the cone getting it off. Epoxy is super strong.

I used some crazy/super/miracle kind of glue on a cracked woofer on my 900's and it has held tight for 2 years or so. Let me assure you if it was a weak link then it would have been exposed by now.

hpm 900- thanks

I was thinking about the epoxy...one plan was to use lightweight fiberglass
tape behind the crack attached with epoxy...I was going to use the superglue
but it did not adhere..
