Liston Acoustics A60 Speaker Owner
I have a pair of Boston A60's. I bought these many years ago and the surrounds were disintegrating. Never seen that before and thought the speakers were done and trash. The sounded thin and distorted. Went on line looking for woofers and found your kits. Was a little skeptical so I watched your video. Liked easy. So I purchased installed and like magic I have a brand new set f speakers. AWESOME!!!!!!!! I watched the video again when I got the kits and followed the instructions. Everything worked as described. The speakers sound like new. Now I have a pair of A40's I probably need to fix as well. Great product and works as advertised. You guys saved me from buying another set of speakers. Thanks so much.

The delivery only took 1 1/2 weeks to arrive from the US. The rims were very easy to fit and now my old speakers are back to new. :)

Ordered this kit for my Boston A70s and couldn't be happier with the results. Surrounds were a perfect fit, and seem quite durable and well made. The included adhesive does NOT give you a lot of working time so make sure you've got the speaker wired up and ready to play a 30hz test tone before dropping in the new surround, because if you need to adjust it you've only really got a few mins to do so before it begins to set. Having said that, its really not a bad thing. I was able to complete both speakers in under an hour and they sound just as fantastic now as the day they were made. Totally recommend this product to anyone looking to revive their old rotted foams..I wish I had known how easy this was back when I was younger..threw out a few pairs that I really shouldn't have.. Ah well. Great product..good price..and most importantly its super simple to do.
