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.

Foam Speaker Repair Kit
Works great. My 7 year old cranked up the volume on my stereo to the max and blew out my woofers on my outdoor Optimus speakers. The repair kit did the job. I got the sealer too, so hopefully the new foam will last longer.
