Ok guys, I am really in need of some help here, so hopefully someone out here can. Here is the deal. I have a MMATS Juggernaut 12", brand new. As I was screwing it into the box, the drill slipped off the screw and poked into the foam surrounding. It is not very big at all, and it's not an actual hole, but if you pull back on the rip you can feel from the back you can tell that it punctured all the way through. What I'm thinking is maybe using epoxy to just seal it up so there is no air leaks and so in the future it wont get bigger. I have some 2 TON Epoxy (the kind where you mix the hardner and resin), but am afraid that the epoxy may eat through the foam. Does anyone know what else I can do to fix this, or know if the epoxy will really eat at the foam or not? Any and all help will be greatly appreciated. Thanks in advance!

there's not to much you can do and i don't think that's gonna be covered in your warranty so i'd just throw it in and go, i don't think it's gonna cause a huge difference in sound

what!?!?! you want some??

No no no, actually it will indeed cause a huge problem in the sound. A ripped surround will not only affect the movement of the cone it will also create an air flow path and your enclosure is no longer effective. It will not only sound like crap, you can blow a speaker operating it this way. Get the surround repaired. DO NOT just glue it up yourself. And yes, epoxy will eat the foam and just make it worse. Do a web search for "Speaker reconing" in your area and see if there is a shop that can replace the surround. If you do want to try and fix it yurself, go to Parts Express and order one of their generic foam surround replacement kits. It will not be as good as original but it will allow the speaker to work properly.

thats kind of funny that you did that. thats my biggest fear when mounting speakers. i always put my hand in the way(over the speaker) if the screwgun were to slip. if i were you i would send it to mmats and get it fixed right. you are going to put that speaker through hell and it needs to be at its best. if you had to repair it right away, i would use silicon to patch up the hole (front and back) and get replacement surround and silicon a 1" piece over the wound. do the best you can do. for piece of mind.

Once again DYohn has words of wisdom. Do just what he said and you can salvage that sub. I know that sucked when you did that. When you mount a sub, if you will put the sub in the hole. Then move it till it's where you want it. Then mark your screw holes with a fine point marker. Then drill small pilot holes. That will make it so you can start your screws by hand, and when they are started good you can use the screw gun.

...........umm, I think your friend knows about it now! Repairing Rip in Subwoofer edge? -- posted image.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

All it takes is one slight false move to stab a speaker sending it to an early grave. I've done this twice(D'oah!), once to a Pyle(who cares!) sub and once to a Kove 10 that I loved. In both cases, I used black silicon glue to carefully repair the tear. The Kove continued to beat my trunk for 2 years before finally succoming to it's wound. The Pyle sounded horrible with the repair. I could plainly see that it was not moving properly and distorted very easily. Now when mounting a sub I place a round wooden template over the sub leaving only the screws exposed, kinda like a bullet-proof vest for the sub. My best advice, be more careful!

I hate that sinking feeling you get after doing that :( I am with dudek38, I position my hand to take the brunt if the screwdriver slips. Thank goodness it was on one of my first subs, a Legacy 12" sub, and the repair would be more than the sub. I lucked out on using silicone as well, but thank goodness thats been the only time I have done that.
