The foam replacement for the Boston Acoustic speakers included the special cement. I was able to repair 2 speakers whose woofers had lost their foam mounting over time. The 25.00 price seems a little high for small pieces of foam and cement but it did allow me to resurrect speakers that would cost 300.00 to buy new.

I am very happy with the repair kit. The youtube video showed just what to do. My speakers are now as good as they ever were. This repair kit saved me a ton of money.

Easy repair, High Quality
The repair parts arrived quickly and with the help of the online videos available on the website or through Youtube the repair of my speaker was simple and painless. I did have I little difficulty getting the correct amount of glue on the speaker cone and smeared it onto the cone but not much. Getting that right would come with practice and as I was only doing one speaker I wasn't going to get much. I will be re-foaming some more speakers later from my car when I have time to do so and I will be ordering more foam surrounds from Simply Speakers to do the job. I don't feel that disposing of perfectly good speakers is a good idea. especially when they are expensive or irreplaceable. I recommend that before you throw out your speakers consider repairing them with a new foam ring from Simply Speakers, it is much less expensive than new speakers and will restore your speakers to like new condition.

Easy system to use. Just be patient and take your time. It probably took me longer than expected but that’s because I decided to do so. Was able to fix a subwoofer speaker that would otherwise have gone into the garbage. Great product.

Between the great instructions and YouTube, the operation was a great success. Good prep is the key, found that Goo Gone worked well to remove old glue. Reconnected speaker, gradually increased volume and patted myself on the back!

Easy to do with patience, glue consistency can be a little tricky but the results are worth it. Don't hesitate to bring your speakers back to life with this kit!
