Springfield Speaker 12" Pro-Grade Speaker/Subwoofer Chip Gaskets - Pai - Adhesive Included

Worked great, just prep well, follow instructions and use w care. Has held up great over the years and still going strong.

There really isn't enough glue so use it conservatively.

seller did a first-rate job of packing this for shipping as any chip-gasket is rather fragile especially at the fastener cut-outs. Great quality item but know that you MUST handle with the utmost of care because it will tear easily at the holes just by the nature of a compressible fiber gasket. Just the ticket for my project and a great way to add a little extra cement-security to the surround on a "hyperactive" subwoofer like mine. (yeah--I like bass because I play one, ha)

They work perfect, and the instructions were very clear, the only thing is that it took way too long to get it! That would be my only complaint, and that could have been through the postal service preventing the timely arrival.

I've only used one in my Leslie Speaker to get a tighter sound; they are easy to work with & tighten up the sound.

I Received these items damaged so I requested a replacement and received a new set a few days later. Tried installing the new set only to find out that they don't fit and I ripped both of them trying to make them work. Very fragile and very cheap adhesive included as well. I wouldn't recommend this product. Good customer service though! for that 2/5 stars

Bought to recone 2 J&L 12 inch subs and they do the job!!

Provides solid reinforcement for the surrounds and a professional appearance,
