Good kit and product
The kit was comprehensive and restored the performance of my Ensemble II satellites. The included glue is very forgiving to mistakes and easy to clean up.

I have been using, installing and repairing Henry Kloss speakers most of my life. They are well built and if maintain can last forever. I still have a pair of AR10Pi that sound and work like new. Thanks to Company's like Simply Speakers. Not only do they supply the needed parts for most speakers but they also educate you on how to properly maintain most speakers. That's not always easy to find. And they do it at a cost that makes it possible to repair just about any speaker. We live in a throwaway world were most of the things we throw away can be repaired. Simply Speakers makes that possible.

Great Sound After Repair
I was so happy to find out there was a way to repair the deteriorated foam on my Cambridge Soundworks speakers. I thought they were destined for the trash until I found out they could be repaired. The repair kit restored them to beautiful sound. Definitely watch the video recommended in the instructions because the written sheet does not explain clearly the necessary details to do it right. Once the video has been viewed, the instruction sheet is clearer. As another reviewer pointed out, the process is quite forgiving and perfection is not needed.

I really couldn't tell where the old surrounds attached as there wasn't enough foam left to tell. Due t the design of the speaker, I attached to the front of the cone. It was an easy project, made a huge difference in the way the speakers perform.
