Do you "treat" your speakers rubber surrounds?

Armorall has silicon and I wouldn't use it or anything else that contains it.

Hey Ehaller and Cytocycle:,

Right On! I discovered 303 Protectant a few years ago (at a sailing shop) and use it on my vintage '98 993 Porsche Carrera dash and the Carrera is definitely worth more than my HiFi rig, so I definitely have had great success with it. I have not tried it on my speaker surrounds since I have MG 20Rs and thus no surrounds.

After moving to California and its associated dry climate, I have found many dry-rotted surrounds. My Sunfire subwoofer manual recommends using mink oil on the surrounds. I treated all my woofers with the mink oil and it seems to work well so far.

I've seen too many speakers with rubber surrounds from the 70's that look and work fine, maybe better.

Usually only foam surrounds dry rot.
