JUST THE TICKET! Materials came quickly and as described, parts fit perfectly, video aided "how to". My speakers from back in the 60's are playing as if they are new. Love the big speaker boom of the bass notes. I couldn't be more satisfied. Great company to deal with!

The foam repair kit installed easy and the end result was reviving an old set of speakers for around 25 bucks that most other folks would have thrown out.

Great service and a good product. Product was delivered promptly. Very complete directions as well as great "how to" video on the website. More than enough glue included to get the job done. Easily repaired a pair of speakers. I would purchase again and recommend the product to others.

Realistic 12" Woofer
I am very happy with this purchase. The instructional video was very helpful. The support staff answered my questions promptly so my repair was not delayed. The profile of the replacement foam does not match the original exactly but It does not seem to have a detrimental effect. It took about 4 hours to do two 12” speakers but half of that was glue drying time. When you consider that the speaker would be trash if not for this product what do you have to lose by trying it? I recommend watching the video several times before starting.
