Worked great
Saved 4 5 inch speakers. Also did 2 12 inch Cerwin vega speakers. Small speakers more difficult. All turned out great.

Awesome !
I was looking for replacement speakers for my Optimus 1000 speakers when I happened upon this website. I searched for replacement foam edges for my speakers and they had them. I watched the video online about "easy repair" and thought it did loook pretty easy to do. I ordered this kit for the 5 in mid range speakers and it was so easy to do. My speakers are as good or better as on the day I bought them. Excellent service, great repair kit and good instructions with video (online) add up to a very good deal.

Had a pair of hi end outdoor speakers stored in the garage. Decided to hook them up, to no surprise, they were shot. Took off the screens to see both foams had totally disintegrated. Went online & found your replacement kit, great price, delivery, instructional video, product and customer service. Wish more vendors were like you. Both speakers reborn, sound great again, THANKS!

A bit of a tedious procedure as trimming of the foam was required, however the product worked well in the end.

The speaker foam repair kit worked perfectly. I had to trim the outside edge slightly but that was expected. The original foam was mounted under the cone, but I mounted the replacement on top of the cone as the instructions indicated. The speaker works great again. I was going to throw the speaker away until I found the Simply Speakers repair kit.

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.

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!
