Treatment for Faded Heresy Woofers

[stevep2007]

Hi Folks

I have a vintage pair of herasys. Puling the grill I noticed that the woofers have faded to grey.

Is there any treatment that will renew them so they are black and won't crack.

I'm the original owner and plan on willing them to family. )

thanks

Hi Steve, I have inquired about the same thing... The suggestions I was given was a black magic marker, or spray paint. The paint was the direction I was going to go because of something I read about acid in the markers. I have not done it yet. Use masking tape and don't get any on the surrounds. The advice I was given stated they had tested it on a junk woofer and cut it in half after testing and applying paint. The paint stayed on the surface, it didn't bleed and it didn't effect the performance. But again this is all hearsay and second hand, not much good as I didn't test any of this myself. Good luck, I too will be handing mine down to my kids. Hopefully my father is reading this too...

Michael Colter used some SEM black vinyl spray paint, IIRC. A very light coat to cover the grey. It was a long time ago that he posted... not sure if the old thread could be found.

I have used stuff from Parts Express I believe is called "Speaker Black" with good results. Never on a Klipsch speaker though.

Googled with no luck, appears its called Wet Look.

The shoe dye works best.

Any treatment could alter the sound, shoe dye might have stuff to keep leather soft etc.

Would be good to see some before and after parameter tests.

The shoe dye has the least amount of solids of all the items suggested, and does not change the parameters (which is why I use it),.

Yeah but the spit shine takes forever on this dye!!  Just kiddin.

As always, DJK you come up with sensible practical solutions.  I'm gonna try that on some 1975 Heresy woofers that need a little attention.  Thanks for the tip.

I used the leather dye on my Cornwalls and it turned out great.  I had to do it twice on the most faded woofer, but it dried superfast and I can't see how it could have done anything to the paper.  Worked great!

I'm going to try it on my hair.

It may be good for coloring recessed speaker cutouts. You can wear out a sharpie in a heartbeat
