I have an old M&K subwoofer that I bought in the 80s (!) It saw some serious loud rocking back in the day, but now it has been relegated, along with the bookshelf speakers, to TV duty. When the loud bass from some movie shreaded the foam around the cone, I didn't know what happened at first. The local audio store said a replacment unit was about $1200 for the whole unit (powered subwoofer), or ~ $200 for the speaker. I decided to try to repair it instead. The instructions were easy to follow and the foam set up very quickly with the supplied glue. The unit sounds good as new! I highly recommend this kit.

Great for MK 5000THX
We used this kit to reform our MK 5000THX subwoofer and they worked great. Easy to install, customer service on phone/email was great. The glue is tackier than you'd think from the videos, it sets quicker than I expected but overall we have a great result.

M&K MX5000MK2
After finding my lovely M&K Sub had eaten it's way through the surrounds after about 10 years, I wondered about replacing them for a while before finding out there was another alternative! These kits are really easy to use and perfect for the job. Remove both drivers. Try and save the Gaskets - you should be able to. Take your time cleaning and preparing! Be aware that none of the drivers are actually glued to the cabinet - just become stuck to the cabinet over the years - especially the vertical one! You may need to persuade it from behind CAREFULLY! Also glue the foam to the front of the driver when re-foaming - even if it looks like it was originally glued to the back. Please view the Cerwin Vega re-foaming video in detail. A very good quality kit indeed - well worth every penny. All worked very well and sounds great again! Many,many thanks to Simply Speakers!

M&K mx-90
Purchased this kit to repair a 1992 M&K mx90 with two 12 inch drivers. Getting the old foam and gasket off was a bit of work but the new foam went on easy and centered up very nice. the seal is perfect and the drivers are like new again. Follow the video instructions and it will turn out very good. Great value!

This was my first speaker repair. It is a M&K V2B. It went pretty well I suppose - I thought the foam was not quite an exact fit but good enough. At the same time I replaced some capacitors in the amp (this sub is 30+ years old) and the sound is as good as new. I like that I still have the original “Deep Base” dust cap.

I thought I was cooked when I heard the sub speakers start to rattle. I decided to check online and of course I found my solution. I watched the video on and placed my order. The product came and went together just like the video. I couldn’t be happier! Thanks for a great product!! 5 stars all the way!!
