Difficult with Realistic speakers
This was a difficult fit for the set of Realistic speakers that I had. This was the second time I've done this kind of repair, the first on a pair of Ohm speakers. And that went very well. But I had to do some trimming to make this fit and it was doubly difficult because the Realistic speaker was such that the foam went behind not in front. Despite doing what I thought was a botched job, the speakers did work. But if you have speakers where the foam needs to go behind the front bevel, consider sending them in to Simply Speakers to have them do it.

recent retired broadcaster
The foam repair kit for our Optimus 45 speakers (bought in 1986) arrived quickly. Hardest part of the whole project was removing old adhesive and foam from the speaker. Thankfully, the Simply Speaker foam replacement video we saw on the company website did a thorough job of explaining the steps and gave us the confidence to tackle this. We trimmed between 1/8 and 1/4 inch of foam away from the interior circle of the new foam since it seemed to cover more of the speaker than the original foam did. The actual repair process was under 30 minutes per speaker not counting the one to two hours we waited for the adhesive to dry per the instructions. The speakers look and sound great after this very simple repair.

The speaker foam kit was for my old (30 years old) Cannon TLS cabinet speakers. Back in the days of component sound system, big box speaker were the best. This kit and the video support made it simple and almost fool proof to remove the old foam and replace it with new. This fix should outlast me. I was extremely impressed with the new sound quality, my speaker have never sounded so good. Almost worth purchasing old speakers on line or at garage sale and rebuilding them. There is nothing like these big old speaker boxes with 8 to 12 inch wolfers.

Ordered new foam repair kit for my 33year old Realistic Optimus 110 tower speakers and received them in only 4 days. Everything I needed to repair in kit and instructions made repair easy. Now my speakers sound like new.
