Fit like a glove and the install was straightforward and simple. Repaired speaker sounds just like it did when it was brand new. Highly recommend this item to anyone with a speaker that it fits.

Was going to toss my Boston A40 shelf speakers and get new one's until I saw your video. Looks simple enough and will give it a try. Very good instructor.

Home Owner
Foam needed slight trimming and regular scissors worked well for that. I replaced foam on 4 speakers and could have used a little more glue. Ran out half-way through the 4th speaker on the last step when trying to add a top coat over the foam-to-outside edge (which was already glued from previous step). I'm sure it will be fine, but I did use every bit in the single tube which came with the kit. Directions were clear and easy to follow. For removing the old glue I found Goof Off product worked well. Speakers are like new again!

I followed the instructions on the videos and the product worked just as described. Changed a 30 yr old set of bookshelf speakers to working like new and in use again in my shop. Most difficult part is removing the old glue from the speaker cone and baskets. Very good product. Bought another set for some Advent speakers.
