I thought your foam repair kit was easy to use and the speaker's sound as good as they did when they were new in 1974. I will use your service again in the future and have already told friend's about your company. Thank's

This kit worked quite well. The adhesive (tube of glue) is clear. It spreads quickly but dries after a few minutes. The videos helped me in the steps to proper alignment of the cone without busting out the dust caps and using those shims!

old speaker enthusiast!
Perfection! These speakers I purchased back in 1982 are now back in service & cranky out an as–new sound. They had been stored the past 15 years & had completely perished. I always dreamed of restoring them one day when I could find the right parts. Simply speakers had the solution.

Product Works Great
I'm really glad I found this company. I almost threw away 2 pairs of speakers due to crumbling foam edges. The repair kit was extremely easy to install. Speakers now sound like new!!!

New Life for Old Speakers
Replaced the foam on my Marantz 12' woofers purchased in 1982. I am very happy with the rich, beautiful sound they again produce.
