Pioneer speaker foam replacement
Years ago (1980"s) I put some very nice Pioneer speakers into storage. Last month I decided to make a set of speakers for surround sound system. I dug out the speakers to find they had deteriorated, all the foam around the cone was gone! I was going to through away these speakers thinking they were beyond repair, but decided to check YouTube so see what others had done in this situation. The first video that popped up was by Simply Speakers. I watched the video and was convinced I could save my old speakers. I ordered the correct kit thanks to their easy to follow website. The foam kit arrived just days later. I followed the enclosed directions and watched the YouTube video and in less than an hour I had perfectly working speakers. Now I am made at myself for throwing away speakers I could have fixed in the past.

Bringing my sound system back to life!!!
I ordered this set of speaker foams as last resort and was able to give a second life to my sound system. BTW these were very simple to install and the result is very close (if not the same) as original sound!! Very very happy with product!!
