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.

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!!!

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.
