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+

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.
