Foam Guard-Speaker Cone Edge Sealer, White PVA, MI-1291FG, 1 Ounce

I used this sealer and new foam edge pieces to repair a pair of Paradigm outdoor speakers. Both were very easy to use, the instructions were clear and the result was a "like new" pair of speakers. I swear they sound better!! The folks at Simply Speakers were very helpful and the shipping process was fast and painless, even up to here in the Great White North. Highly recommend these parts and the folks at Simply Speakers. Cheers Mike

Foam Guard works great... all speaker surrounds now completed... could increase bottle size... seems a little expensive...Overall satisfied with results.

Exactly what I needed to treat the delicate paper surrounds on the vintage 1984 Panasonic RX 5250 boombox I'm restoring. Speakers should last another 30 year now!

A little early to tell if the foam actually lasts years longer after the treatment, but it does give the foam a stronger feel and the speaker sounds great. Plenty of product in the bottle to treat the next couple of speaker repairs if the need arises.

I have used this product on some of the larger speakers, but I wish the consistency was a little thinner for smaller speaker foam surrounds. This Edge Sealer smells like Elemer's Glue. Seems to work pretty well. I used a softer brissle brush than the one provided. You have to work fast because this sealer sets up fast. After a sealing one speaker, I'd advise to clean your brush throughly before starting on the next speaker.

As a life long audiophile, and a college physics teacher, I want to endorse the MI-1291FG Speaker Cone Edge Sealer. I have four 15" subwoofers that have served me well for more than 15 years. The edges have begun to appear dry, weak, and two even had small tears. I followed the directions precisely (and recommend you do that too, and they are well written) and 24 to 36 hours later they were totally dry to the touch. The two tears were totally mended, and the speakers work perfectly now. Yes, I drive the bass drivers hard, sometimes. And they continue now as though there were brand new. I endorse this for ALL audiophiles, of all ages, and all sizes of speakers.

If you have older speakers with foam surround that have held up through the years, this is a great way to protect them and avoid having to refoam them anytime soon! Turns light grey foams into a darker grey color though.

Used this product to seal the newly installed surrounds in my Acoustic Research AR-2ax speakers. Also treated the surround in an older Infinity subwoofer to preserve the foam life. I feel confident it will help and haven’t noticed any negative effect on sound. I would suggest to practice on an older speaker first. Make sure the foam being tearing is free of dust to prevent particles being trapped. Also, I found this product gets tacky fast so I would wait until after the applied product is dried before making tough ups. I did not do that the first time I tried it and it resulted in a slightly rough finish with streaks and not the smooth, streak-free finish I desired.

I have applied Sealer and will have to wait to see how it protects the foam. That being said, it went on as advertised and was easy to apply with a simple paint brush

Excellent product ... much better than replacing the speakers.
