My JBL L166 studio monitors are back up and performing like they never stopped. I can't stop smiling. My studio never sounded better. Rock on!!

I've used Simply Speakers foam kits before. These worked pretty well. I thought they were just a tiny bit undersized for the JBL 128H to where I almost had to stretch them - a scary proposition for sure. All good in the end functionally, though if a little sloppy cosmetically from glue smears as I kept pulling them outward to fit.

The repair kit has worked fine so far. I have not yet applied heavy load to the woofers, but they seem to work just fine.

There are a lot of companies that do foam repair kits for speakers and not many ways to decide which kit to buy. An easy way is to view their instructions ahead of time. Before ever ordering I watched the video on repairing my 128H speakers. It covered things I didn't know ( differences in diameter cones ), and fully showed the repair process. Not only that but Sean Ryan ( guy in the video ) actually looks like he's talking from experience unlike, the other videos I viewed. Honestly he looks like he could re-foam a speaker in the dark... Anyhow, warm fuzzy feelings that if I hit a snag I could call someone and they'd actually know what I was talking about. Plus other kits I looked at really do seem to come with the same white glue that we ate in kindergarten. The quality of the foam seems good too. Anyhow, after watching the video and reading their instructions I re-foamed two speakers on my kitchen counter in a Friday evening with no trouble at all and the speakers sound great once again.

Great Repair Kit
I have had a pair of JBL L166 for about 30 years and I love these speakers. There is nothing on the market today that compare. This is the second time I've refoamed the woofers. The repair kit fit perfectly and the how to video was excellent. It told me step by step exactly how to remove the old surround, prep the cone, install the new surround and position the voice without shims. The repair turned out great and speakers sound like they just came out of the factory. Great job Simply Speakers!
