Terrific customer service and product. My speakers were not in the data base, but service adviser took the dimensions of the cones and frames and matched them perfectly with a kit. The install went well but had to improvise with the glue attachment, doing cone and frame simultaneously do to their small size and close approximation. Whole job turned out super and now I have my system back up and it sounds terrific. Thanks to all involved in my order. Best. Michael

I used these surrounds to replace the deteriorated surrounds on my mid range sealed speakers in my S40’s. Had to trim a small amount on the outside diameter and then they fit perfect.

Refoamed Koss M-80's. Used 4 inch kit with front mount technigue. Sounds like new. Excellent product to save a great speaker. The secret is the special adhesive included with the kit. Thank you.

Fantastic - Saved me much money by not having to purchase a new Woofer Speaker, I measured my speaker mistakingly and had to change the order, so Simple Speaker helped me get the correct one. The use of my repaired one is better than I ever expected it to be. I've got my music in my Roadster "cooking" better than ever. Thanks so much

Foam kits fit perfectly, simple to install, thanks to detailed installation video. Speakers sound great and should last for another twenty-five years. Great solution.
