I have a ~40 year old set of Cerwin Vega V 29's and i'd like to try to sell them but there is a buzz in one of the woofers during heavier bass tones.
It seems like it might have something to do with the voice coil or other components inside the woofer.
It fades when pressure is applied to the surround in certain spots so there could also be an issue with the surround.
I checked the spider and I don't see any sign of tearing.
I don't think I want to attempt a recone myself but i would like to know the cost and difficulty involved so that I can price these accordingly.
How do you keep a recone vintage original spec? It's basically replacing nearly everything that makes a driver sound as it does.
Do people normally do original spec recones or do they just put whatever they can find in there?
I'll give that rotating trick a shot. If it's sagging the surround would have to be replaced in the long run right?
Unfortunately I think I may have damaged these awhile back. I had some infrasonic tones from a bass guitar and they may have been pushed a bit past their limits.
Nah, I was silently flexing a string without paying much attention to the woofers.
Then when i eventually noticed the woofers flexing around 1" I of course had to show off the ridiculous excursion to the band.
Little did i know that woofers don't always make loud noises when they partially fail. Assuming it has taken damage to the voice coil and isn't just out of alignment due to the surround.
