Awesome Foam Repair
I had two 12-inch woofers that I was ready to throw out, they were actually in the trash can when I came across this foam repair kit. It was a good price so I thought I would try it. Sure glad I did, it was very easy and practically restored my woofers to new condition. Instructions were very clear, just make sure to keep pressing on the glue over and over until it sticks fast; when it is liquid, it doesn't have the sticky power like as it dries, then it sticks the foam down strong. I recommend it to restore old speakers.

Yes I got my speaker repaired and the video and kit made it a simple task. Thank you so much for offering this kit along with the information that gave me the confidence to do it myself.

Optimus 12" woofer surround
The voice coil did not line up as well as a set of D5 Cerwin Vegas that I rebuilt. I had to resort to using a shim to get this one right. Optimus is not a precision frame so I was not surprised. I am pleased with the results.
