The repairs worked exactly as described. Saved a lot of money and retained the sound quality I expected.

I had a pair of old speakers that were built into the wall as the surround rear speakers. Couldn't find any new speakers that fit the holes in the wall so it was nice to find a skit and refoam them which did work. Thank you

The 5 inch foam kit was a much better fit to the cone and frame compared to the 15s I refoamed they also were much more manageable. Also I used acetone instead of the 91% alcohol and it was so much easier to clean them up and there was enough glue as with the 15s I barely had enough to finish. I still haven't pulled the rack stereo out of storage to hook them up and test it out and then sell it all Kenwood 150 watt per channel, Eq, remote preamp controller and realistic Mach 2 speakers Circa 1986...they should sound awesome again will let you know.

Product works as advertised. Fairly simple to install. Having a bottle of isopropyl alcohol and cotton swabs is an essential part of your tool kit. Take your time and follow the instructions.

This is a great product. I have rejuvenated 3 pairs of speakers, with great results. The most recent is the Optimus LX5-II with a 5" speakers. The original foam is glued to the back of the cone, with the repair I glued it to the front, it still sounds great.

The foam on the midrange speakers were crumbling, it was easy to remove the old foam, just watch the video. Installed the new foam, added the glue and let dry. Good as new.

Don't buy new speakers, rebuild!
My old beloved Optimus dual center speaker began rattling one day. I was prepared to either buy a new one but it fits perfectly in my entertainment center. My second choice was to replace the speakers in the enclosure for about $100 or more. Then I found Simply Speakers Foam Speaker Repair Kit, I thought why not give it a try for a little over $30. I was a bit nervous about installing new rubber surrounds but the instructions were easy to follow and the project only took a few hours and I am so happy my center speaker sounds like new. Thanks Simply Speakers!

Good product, great customer service. Installation is not quite as easy for a tyro as it looks on the videos, but it is doable and in my case the end result is sonically perfect even if it doesn’t look so neat.
