I bought a Alpine type-R broken for $7.50, all i need to do is glue the surround back on to get it working again. What kind of glue is best, i was thinking black silicone? Theres no rips or anything, it just came un done from the cone. And is there anytricks i should do it fix it?

Im sorry you spent 7.50. If this is one of the old type r subs, get ready to spend alot on more surround material. and prepare for the tinsel leads to break...It sounds already like one of the first year Type R subs that gave me nothing but probelms. You can attempt to repair it, but I would turn around and sell it after its reapired and working

I have replaced a few surrounds before. i used standard silicon to seal the cone to the surround. Just to be sure they didn't seperate, I sealed both the inside and the outside of the cone/surround.

I dunno if it will work, but i saw a kid use JB Weld epoxy when gluing the spider back onto a cone. It worked like new afterwards, and the seal still hasn't broken. If the epoxy doesn't react with the surround material, use that, then seal it with silicone. ------------- ~WAYLAND

We use Prism 410 by Loctite. It is very expensive, but works great. It is designed for speakers. Here's a link: https://www.loctite.com/int_henkel/loctite_us/binarydata/pdf/lt3273_SpeakerAdhGuide.pdf Steven Kephart Adire Audio -------------

Steve , do you know where i could get some?, i couldn't find it anywhere in town. The black silicone i tryed didn't work, it was to soft, it worked for 15 min until i played Get Low. Definately should do it right and get the good glue since im powering this sub with a MRD-M501.

K, i found it online, , it comes in a 3 gram tube, or a 20 gram bottle. Will 3 grams do it?

Ya where i work we use loctite. We make led arrays for machine vision we use uv curing loctite expensive stuff it is, i heard we pay like 250$ for about a pint.
But it's cool we have a uv machine you just put your loctite on aim the led then hit the pedal for like 5 seconds and the glue is cured. I would like to have some for home use but the cost of the glue plus the uv machine is way to much.

I say give JB Weld a shot. They have a lot of different applications, and their WATERWELD line may be exactly what you need. Before you spend a fortune on Loctite, give this stuff a shot. It costs like four dollars, and can be picked up at a hardware store like the Home Depot.

The 3 grams should work (as long as it's the small tube). And yes, it is very expensive. Good luck! Steven Kephart Adire Audio -------------

Try this out https://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=340-076 It's made exactly for what you want to do. I have used this before on different types of surrounds and cone materials and it always works. You will be amazed at what kind of damage my friends inflict on their speakers.

I ordered up the prism 410, got 2 , 3 gram tubes just to be safe, , it cost about $11, not to bad . When glueing surrounds back on, should i make a jig to hold it down tightly?
