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.

This product was outstanding. It was rather easy to install, and my 14 year old speakers look and sound as good as new. The installation video and instructions were particularly helpful.
