Ordered this kit for my 20 some year old speakers. Just like other reviews, it was easy and took me around an hour of actual work to complete. Everything in the kit was perfect. A+

Good stuff, but make sure you measure!
I didn't buy this kit, so why review it? A couple of things bear repeating, and reading this might save you some frustration. Originally, I ordered the FSK-15A kit without measuring the cone diameter of my Mach 2 woofers. The FSK-15A kit is for 15" woofers having 12" diameter cones, while my particular flavor of woofers have 11-3/4" cones. One size does not fit all. I made a hasty change to the order and got the right FSK-15MACH2 kit. Yippie. The other notable point is Simply Speakers was a breeze to deal with, and their videos are invaluable, especially if you've never refoamed a woofer. It really was as easy as it looks. In fact, the hard part was cleaning off the old foam. Fit was perfect, and the cone virtually centered itself. Based on experience, I would have no qualms buying this kit after confirming required dimension.

Repair was successful and I have been enjoying the clear sound since. The only reason I have rated at 4 stars is because for the model of speaker (Optimus Mach 3 #3807) I repaired, I questioned whether I had enough inside material to cover sufficiently. I had to be precise with the foam placement. If an additional 1/8" or even 1/4" of material was on the inside circumference, it would have allowed for easier and more confident installation to this newbie.

Great product. Fit our 15" Optimus & Realistic speakers perfectly. The foam repair kits were easy to install utilizing the detailed videos Simply Speakers have available on their website. This was our first time repairing speaker foam and it turned out awesome!

The refoaming of my speakers was easier than it looked..the product was easy to work with and directions were great....Great Product, just follow the directions and the speakers will turn out great..Though one suggestion work with a little bit of the glue on something other than speakers to see how it sets up (drying time)
