ok

I got a pair of klipsch kg 5.2 speakers a while ago.

one of them every so often would make some sort of rattling sound from the 10 inch driver.

I took a look at the driver and found a small hole/tear in the rubber surround.

about 4mm by 3mm or so.

Nearest the outside edge next to the frame of the driver.

I bet I was hearing air leaking out the hole.

what should Use to patch the hole ?

will the acid in silocone or other glues damage the rubber ?

how should i apply it so that the repair is not visible ?

do i have to put a new surround on the driver ?

Go to your local Toyota dealer and buy a small tube of Toyota Black sealer.. it is used to seal oil pans..

It is made of Butyl rubber (the same rubber most surrounds are made from).. With some care, you can patch it very well, take your time and let it dry over night..

Try to match the thickness of the original surround or slightly thinner, not thicker, don't just blob it on, use vaseline, or lip balm on your fingers to shape it..

I have repaired many surrounds this way, Originally, I thought of it as a temporary repair but it wound up being lifetime repair..

I discovered this while repairing a 13W7 JL audio sub in my car (large tear in surround) took my time, repaired it with the toyota sealer, and it sounded good as new for many years, I still have it... repair was over 5 years ago..

WOW ... thanks for your advice .. This sounds like a great solution :thmbsp:
 
I have also used bicycle innertube repair kits. They may not be as good as the Toyota sealant recommended by Sk8, but provide most of the essential items.
 
the toyota sealant sounds great - thank you.

It is actually a tear or flap that mostly re seals itself when the driver is not moving.

I got the speakers at the salvation army for 30 bucks on 1/2 price day.

blonde oak veneer.

i wonder if the tear has been there from the factory ?
 
the tear is so close to the frame and small

not easy to see when it sorta re seals itself
 
i have bought that exact tire repair kit for years.
it is the best


i might even still have one somewhere

i think it uses regular rubber cement
 
Love the Toyota Black Sealer advise, I'm sure there are other equals to the Toyota. I've used silicone few times with great success.
 
this thread caused me to go look at my poor old canondale road bike

the tires hold 125 psi

time for a ride
 
It's a cold vulcanizing cement. According to the original thread, once it dries the glue line almost blends into the original butyl surround material.

I have a woofer that needs it, but haven't done it yet.
