Its a good kit
My friend recommended Simply Speakers when I needed to refoam my Optimus Pro 77s. The 77s are great speakers, and when I noted that they were started to make "poommfff" sounds, I was worried that they were dead. For a little less then $30, they're back up and running.

Product performed excellent. I myself did not apply the foam, but I am told although tricky it was not hard. As many have said second one was a breeze. I am so happy to finally have a great set of old speakers new again

My 30 year old Optimus speakers sound as good as day one. My order was quickly processed and delivered. With the help of the provided instructions and on site video's the repair went extremely well.

I used this kit to rehab a speaker for a friend. It worked well although I had to attach the foam to the underside of the cone as it had a better surface to glue to. The online video's make it a snap. You won't be disappointed.
