replacing rubber surrounds with foam

Zymrgy · 4th January 2004, 05:17 PM

I recently decided that I need a new center channel for my home theater. I went through my collection of old parts and I found a pair of 5 1/4" speakers, Kevlar coned Versa-Tronics. A few years back these came out of a car that I had. They are pretty impressive looking...cast basket and all. Upon closer inspection, I noticed that the surrounds had developed a few small tears in them....it almost looks like they had been cut. (worst one is about 1/2 inch long) Everything else on them looks great.

I searched around and I have found several places that offer foam replacements, but not rubber. I did see another post here that mentioned a place in Australia that had rubber surrounds, but I can't find any here in the states.

What I am wondering is if replaceing the rubber with foam would be a bad thing? I know this would affect the T/S parameters some, but I am thinking not by much. I am having trouble finding the parameters for these anyways....

Versa-Tronics EOB130R-KVC/8

Thanks all for your input!

If the surrounds are actually PVC vinylweld solvent can fix them,
alternatively rubber cement can be used for real rubber surrounds.

Changing PVC/rubber to foam is not a good idea, as termination
of the cone edge will change drastically and effect the midrange.
