Treating speaker cones


Someone told me that there is something to put on my 15 year old KEF speaker cones to extend their useful life.
Anyone knows what fluids can be used to keep the plastic and or cone in good shape.

dcaudio: i think the liquid you're thinking of is glycerin. it's at least worth trying. could be your speakers have been in a coastal environment all those years. -kelly
Foam surrounds need replacement often. Fortunately for you KEF uses Butyl surrounds, which last a long, long time. If the speakers sound fine, I'd sit back and enjoy the music. Apply chemicals to cones and/or surrounds is iffy at best.
That should have read "applying" chemicals. It is 7:00 A.M. and I'm not running on all eight cylinders yet. Need more coffee.
Thanks everyone. Seem as I may have listened to too much to Mr. Magician. Speakers still sound fine. But the audio bug makes me continue to think about tweaks.
I use Maguires tire dressing on my speakers-keeps the butyl from drying out and for speakers sans grills it adds a nice shine.
