Graphite repair

[The Rebel]

Hi. Working on my HPM 900s, I have two small cracks less than an inch long in each woofer. I have read where people are using what they are referring to as "carbon fiber", or "carbon fiber paper" epoxied to the rear of the cone for the repair. I have yet to find anything like what they are describing.
Is there an alternative material to patch these woofers? Thanks

Try googling carbon fiber fabric.

Try googling carbon fiber fabric.

Well, that was easy. Now I need to find some local for a small patch. Thanks for the tip, hard to believe how hard headed we get... -

I hate when I'm looking for something on the net, and I'm using the wrong terms. I knew what you meant, but it took me a couple tries to find the right word.

Try a bike shop.

Hi guys,

didnt want to open a new topic, so i post my question here. I realized 1 tear on my HPM-900. For me it seems that only the surface damaged. Should i worry about this now? i dont have experience in gluing woofers, so wouldnt touch it if its not necessary.



thanks

For IMG I found black fingernail polish works great. Had one of my kids knock over the Infinity Modulus Speaker and stand, the grill framework punched a hole right through and left a radial crack running the full distance middle to outer edge.

I used fingernail polish to affect the repair and 20yrs later it still operates as new. I replaced the mid/bass drivers in both about a yr ago but retained the old just in case.

If your bass driver isn't black then pick whatever color polish is the closest.
