Hi,
I'm replacing the surround foam on my AR11 woofers. About 25 years ago, I had a speaker repair shop in Dallas replace the original foam and now I'm wondering if they did it correctly.
The outer edge of the surround is glued on top of a hard gasket that is glued to the speaker frame. Is that normal? Whenever the articles and videos that I've consulted deal with gaskets on woofers the foam surround goes between the gasket and the metal frame, not on top of the gasket. On the other hand, the pictures of AR11 woofers that I've found on the Web do seem to show the surround on top of the gasket.
Should the surround be glued to the top of the gasket or be between the gasket and the frame?
Another question I have is on how to remove the adhesive that the shop used on the foam. The adhesive will soften and get gummy with rubbing alcohol, but the adhesive hardly dissolves at all. The only way I've found to remove much of the adhesive is by scraping with a sharp x-acto knife, but the adhesive won't come off unless I use enough force that the blade also sometimes removes small amounts of the paper cone. This does not seem right to me.
Is there a better way to remove the adhesive?
Thanks,
Al
