My prized HD 440 Marantz bookshelf speakers were sitting for more than 10 years with very little use as the foam rings had dry-rotted and had a pretty bad distortion on certain ranges of notes in the music. I couldn't wait to try the repair kit, just anticipating hearing my music like I used to. My son and I turned it into a team effort as we could share across the place and meaning of music in our lives. The kit worked so well -- ingenious way to install without digging into and tearing the speakers apart. The result was wonderful. Just one tip for those with the same issue: we were able to filet the paper gasket (or whatever it's called) and made it the correct depth. I would recommend this product to anyone, why, I'd be your spokesperson if you wanted me to be. Thanks. Have a great day! Doug, Edinburg, TX

Marantz 8" foam kit
This s the first time I ever refoamed a speaker and it worked great! The online directions made it seem easy and the finished speaker worked perfectly. I have since ordered a kit for my Bose 901's and will be finishing them soon. Thanks for the good product, Bob V.

Great Product
This was the second set of speakers I have used this on. This set turned out as great as the first. I could not be happier with this product. Highly recommended.

I would hereby like to say what a pleasure it was when my 21 year old Marantz HD65 subs was revived with the kit I received from Simply Speakers. I had them replaced with a set of Jamo's at a cost of $400 not knowing that I could have them repaired at a cost of $50!The sound is as great as I have got to know them over the last 21 years! Thanx for the great service and product!
