so i have 2 12" Infinity subs in a ported box w/ an Infinity amp, haven't installed it yet
the cone of one of the subs has a rip in it from the center to one side, will it still work? and is it still worth something?
if i was to sell the whole system how much do u think its worth w/ the rip? its an Infinity 310a amp but don't know about the subs, is the only way to check wat kinda subs to open it up?

if you can glue a patch over the hole, it will still work....wont look pretty, but as long as that patch is SECURED you wont notice much difference than before there was a hole

what kinda glue?
something special and where can i buy it?

This happened to me while trying to fix my sub, managed to slice a hole in it

Anyways!

I used a 2 pack epoxy resin (resin + hardener) Normally found at your local DIY store, Araldite or similar.

Mix the resin and hardener and spread a liitle bit on the back of the cone (if you can, if not on the front) around the hole or tear.

Apply some paper towel as a patch, and press into the resin on the cone.

Coat over the paper towel with more resin. Kinda like working with fibre glass.

Dries rock solid and good as new, if you can get it on the underside of the cone you won't even see the repair.

Happy days

so is it at all plyable? a rock solid foam surround would suck!

well the only way to know for sure if a sub is going to work is by hooking it up. if its blown its not gonna hurt it anymore than it is. and yes if is not scraping on the magnet. then you will be fine with a patch.
nice setup.
i would go with a 1000w rms amp for infinitys though. they will bump wayy harder.
but if you ask me whats the best system you can get for the money.
it is rockford fosgate by far. they give you damn near comp grade subs for a fair price.
you just gotta get the right amp from em. which is hard to find in your local sterio shop.
and for a box i would go with a sealed box in the hatchback. wayy cleaner sound. just as loud with less rattle.

I don't really agree with anything ^ said...


Obviously it will still work with a broken cone/surround. Neither of those parts are essential to its operation, just its function .

The cone ripping is way less of a big deal than the surround. If the surround broke, I'd just put a dab of superglue on the corners of the tear(so it doesn't get worse) and leave it.

If your repair rubs on the magnet, you tore it in a terrible place, or your patch is 100x too big. Its unlikely it will hit the basket either.

I've had a few rockfords, and I hate how they flutter. I wouldn't buy them again.

as for ported/sealed it all depends on the tune of the box/car for how bad you'll rattle. Ported is typically louder.

i think i was miss understood. i was saying patch if the sub isnt off ballence with the magnet. i agree with what your saying about the repair.
and they only flutter in small sealed boxex. which also causes a reverb. but you put em in a nice 2'x1' 6" box they will hit harder along with lasting longer than most brand name subs.
alpine is great too. type r is the shizznit

Now I understand you. It makes sense. I doubt the weight would put it off balance enough to rub. If you look at how its constructed, the cone is held at top 'top' by the surround, and at the bottom by another type of radial spring. Its pretty sturdy.

True, the rockfords I had were in a small box. Tiny. I'll put them in something bigger next time.

Looks like your thread got off topic.^^^ Don't do that guys, get a new thread to talk about your sub choice and boxes etc...

I do not "really" compete or anything with car stereo, but I do like it alot and mess with it. I would use some simple lightweight paper (look around in an art store, paper is measured in pounds- usually denoted with a #, the lower the number the lighter/thinner the paper) on the backside of the cone, glued on with some superglue. Superglue is not flexable, but it is light. The lightweight paper would only be to really give the glue something to stick to. If you can get the sides of the tear to rejoin to make a seam it should be the least messy, and the least offsetting to the voice coil. From the front side it would only look like an imperfection in the cone if you got the seam really nice.
Do not try and run the speaker with the tear in it. You are likely to make the tear worse or ruin the voice coil.

Old thread but for information purposes...
DO NOT use glue wtf? Use RTV silicone, the gasket maker stuff. Its flexible. Trust me, I have used RTV silicone to successfully repair foam/ rubber surrounds many times, aswell as holes in plastic cones/ metal cones/ paper cones.

I'd use glue for that.

He didn't say surround. He said a radial rip in the cone. No one suggested using rigid stuff on the foam surround.
