Do you "treat" your speakers rubber surrounds?

no you should leave them alone. if the manufactor would have wanted to do something else to them they would have.

Absolutely...periodically I treat my woofers by playing some AC DC..."Back in Black" works best. I crank the volume up until I achieve about 1 inch cone travel. This maintenance procedure works like gang-busters to remove dust and gets those Dunlavy surround back to black in no time. Then, I play some Beatles "Rubber Soul" at a moderate level to settle them back in. BTW - please do not use Armor All as our trusted friend Sam T. has done in the past - it's a real reputation buster.

You mention not to use Armorall, but Ty from Tyler Acoustics told me that using Armorall every so often is OK for the surrounds. I haven't used Armorall, but if I was going to treat the surrounds I would use 303 Aerospace Protectant. It's mainly used on a boats vinyl to keep it like new. It won't degrade in the sun, or make the vinyl brittle. I have used this product for 11 years on my boats and I would be comfortable using this on my surrounds; what you use is strictly up to you.

talk to your speaker manufacture...

Ehaller: 303 Aerospace Protectant rocks!!! the only thing in Arizona that doesn't cause cracking.. Armorall really isn't that good to put on anything rubber that you care about..
