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.

Thanks in advance smile.gif

Locally, it costs $75-$85 USD to have one reconed.

But what's involved in the recone?
Which parts are replaced and which parts have to be matched to the characteristics of the original components to end up with the same sound?

you could try removing the driver and rotating it 180 degrees. with speakers of that age, the speaker may be suffering some "sag"

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.

biggrin.gif 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.

Replace the cone, voice coil, spider, surround and cap with original equipment parts. If they aren't available, replace with parts that are as close as you can get. Sometimes the magnet is recharged.

Some go for original, some don't care.

FWIW the cost of the parts is usually close enough to a complete recone from a pro that it doesn't make sense to do it yourself.

Well, i'll probably see what I can get for them then. I don't have 100$ to be putting into speakers that I payed 50$ for, and someone out there will have better use for them than I do.
