Foam kit for Large Advent With Larger Cone
Excellent product made better by very instructive videos. I initially ordered the wrong foam kit for my 1974 Large Advent speaker. It turns out that my speaker had been re-coned with a larger cone at some point and the Large Advent foam kit supplied by SimplySpeakers was too small. After contacting customer service by email, they replaced it at no charge with this FSK-12F kit which fits well. I live in a very dry climate and found that the working time of the adhesive was pretty short but it worked. Now my 1974 Large Advents have a new lease on life! Great customer service and product.

Design Acoustic DA-20LF
I needed a 12" speaker foam surround for my Design Acoustic DA-20LF Sub Woofer (dual voice coil sub). This kit, with a single surround, fit perfectly and was fairly easy to install after watching the online installation video.

I'm so lucky I stumbled onto! I ALMOST threw my Pioneer SW-100 Home Theater Sub-Woofer in the trash! It was rattling, and making all kinds of horrible noise and distortion. Then I found onlline and read; the most common issue with old speakers, is the rotting of the foam surround. I watched the online video of the repair method, and chatted online with the guys at, with some additional questions I had. They were extremely helpful! To make a long story short, I ordered the repair kit, made the repair, and for $20, and very little effort, I now have a sub-woofer that sounds like it did when it was new! Thank You!

Fit into M&K Volkswoofer
I have a really old model M&K Volkswoofer, and this fit perfectly! Originally, I bought the Volkswoofer foam kit, but it did not fit. The guys at suggested this foam after seeing pictures of my sub. Sounds amazing! No flutter or holes at all. Installation was extremely easy! :)

Single 12" Speaker Repair Kit
The speaker repair kit was the best investment that I have recently made. It gave new life to an old speaker. I'm very glad that I made this investment. I would recommend the repair kit to anyone looking to hold on to speakers that just need to have his simple repair. My sub system sounds great again!
