The only problem I ever had was evaporation of the ferrofluid in tweeters. This can be serviced with some tweeters, but mine were not in that class. A sorry problem for a supurlative and expensive speaker, albeit one of a little age. There are some do-it-yourself recipes for a fix, but only a temporary fix. So, I got some new speakers.
Thoughts on extending speaker life.
For those of us who own speakers that are past a few years old, and those same speakers utilize dynamic drivers, what are your thoughts on extending the life of the rubber surround ( assuming that your driver utilizes this kind of design).
In general, as the driver ages, the likelihood of the rubber surround failing increases. Without actually replacing the driver ( not possible in some instances) what do you suggest to extend the life of the driver(s), if anything?
For those with other types of driver design, what are your concerns about the extended usage of this kind of driver as it ages?

Early foam surrounds broke down, but have lasted more than 10 years in my experience. Many lasted 20 years or more. Butyl surrounds don’t have the same break down issue. Accordion paper edges last a long time as well. I have customers with speakers I built in the 80’s with paper edge or butyl rubber surrounds that show no signs of wear. I’m using a set of Eminence woofers from 1983 in my bedroom system. I keep checking for wear but they are still soft an pliant. And sound great. Never treated them. The newer foam compounds being used should last many years. You may not have any need to worry. What does your speaker manufacturer say about life span? |
I’ve read that somebody had bad sound from energy c2. the rubber was stiff. he applied rubber rejuvenation stuff and the improvement was tremendous . the speakers were over 20 years old. my surrounds do not feel stiff ...but i’m itching to use some to see if they would be more flexible . https://www.amazon.com/Max-Professional-2145-Rubber-Rejuvenator/dp/B00363M0TC https://www.amazon.com/MG-Chemicals-408A-125ML-Rubber-Liquid/dp/B008O9X3KS/ref=pd_bxgy_121_img_2/145-1917440-8998167?_encoding=UTF8&pd_rd_i=B008O9X3KS&pd_rd_r=0bb7b184-9bbe-11e9-836e-f5a9254bf257&pd_rd_w=v043L&pd_rd_wg=y9L9j&pf_rd_p=a2006322-0bc0-4db9-a08e-d168c18ce6f0&pf_rd_r=TEDGS9TNSHCF1JFB4DSZ&psc=1&refRID=TEDGS9TNSHCF1JFB4DSZ |
