Instructions and kit are well done. I'm a little bit concerned about the actual size of the foam though honestly - I ordered the specific product for my JBL speakers, and they just barely reach the rim of the speaker frame and were a tight fit to get around the speaker cone. They seem to be working okay, but I'm somewhat concerned that they're going to limit the throw distance of the speaker cone. I probably won't be cranking these up to maximum power, but it seems like the restricted motion of the cone could easily affect the frequency response even at moderate volume. I think that I would have sent these back and asked for a larger diameter if I hadn't been so far into the process of taking the speakers apart..............................Response from Simply Speakers: Thanks for the review! On your JBL woofer model, the new surround is designed to have a space between the outer edge of the frame and the foam. This will not hurt performance in any way. You can crank them up as loud as you like!

Dear Simply Speakers, My experience with your organization was wonderful. The 12" foam edges fit perfectly and the glue performed exactly as described. Your online videos provided me with everything I needed for a first time foam edge repair. My JBL 122A sound great again. Great doing business with you. Best regards, Flemming Denmark

This was my first attempt at replacing the foam surrounds on a pair of speakers. I was given a pair of JBL 120Ti speakers and I thought it would be worth the effort to attempt the repair. The video was very helpful. I can't say I did a wonderful job, a little messy in places but the speakers now work great. I had an opportunity to learn a new skill, which I likely will never use again.

Saved my favorite speakers
I thought my favorite speakers from 1983 were goners but now sound great again. I found this kit which included a video on how to make the repair and could not have done it without the video. The glue was trickier for me but I took it slow and all worked out.
