I ordered this item before I bought new speakers. I was surprised that they came as fast as they did. When I got the time one evening I sat down and installed them. I had watched the you tube video and read the instructions and it all worked out great. I highly recommend these before buying new speakers.

Easier than I thought. A bit messy with the glue but practice would make a difference. I tried both methods, glue on top and bottom of cone. Easier to glue on top but much better centering the coil by gluing under the cone. I also used a label remover called "ATTACK" which worked better than Alcohol to remove old material from the speaker,but you need to use the Alcohol to remove the Attack so that the glue will stick.

Very pleased from beginning to end with this product. It was shipped promptly and securely. The video instructions were thorough and easy to follow. Replaced the surrounds on my Optimus Mach 3's in 2 days (due to other responsibilities) and I am extremely pleased with the sound. To think I was going to just sell them at a yard sale for $20 !! Since replacing the surrounds, I now keep an eye open for other quality speakers for sale in need of surrounds to be replaced. I will definitely be a lifetime customer!

These foam replacements are AWESOME! The instruction videos are great - just follow them and you can restore these speakers very easily- The rubbing alcohol tip in video - absolute best! My speakers are brand new again!

Ordered reform kit to my USA made Realistic Mach 2 speakers from 1984 which are not common in Sweden where I live. Was very happy to find out about Simply Speakers website where they had everything I needed. Simply Speakers feels like a professional company where they keep it plain and simple with good information about what you need. I Refoamed both the 15" and the 8" speakers and everything worked perfectly, also thanks to Simply Speakers YouTube video about how to reform your speakers, since I never done it before. I got a lot of glue on my fingers because it was the first time I did this, and yes, the glue that came with the foam is good quality. See you in 20-25 years when it's time again. /Johan

Speaker foam rings
This is the second time I have purchased speaker foam rings and each time, they arrive very quickly and the instructions are so easy to follow. I am totally satisfied with these products and would recommend this company and their services/products to anyone who is even slightly handy. Simply follow the instructions and renew your speakers indefinitely while saving a fortune.

Great product!
The Radio Shack 15" Foam Speaker Repair Kit, Mach 2, Mach 3, FSK-15MACH2 (PAIR) saved my pair of Radio Shack speakers! I had looked everywhere on the internet to find a place that would re-cone my speakers here in Las Vegas, but couldn't find one. Then I found and learned about their speaker repair kits. I ordered the kit, watched the video on how to use it, and the rest is history - my speakers are like new again! I learned a new skill and will definitely be looking to for my next speaker repair... :-)
