will77530 Posted July 12, 2012 Report Share Posted July 12, 2012 In most cases I would say back presssure i.e. in my spl boxes at 2800 watts I fold cones like a champ hence the reason I glass the cones so I can take advantage of the 7k+ the box is capable of generating. In this instance (I could be wrong) the box appears to be to big causing over excursion and stressing the cone until it gives out. The dustcap is a good indicator of this as well as the stress marks(creases) on the cone. If your feeling adventerous you could glass matt the cone and glue surround back to it and of course gorilla tape the surround. My best advice would be to recone the sub then adjust the ssf up some to limit power to the sub as its fairly clear to me that its at its mechanical limits in that box. my responses all came from things rob has taught me over the past year Quote Link to comment Share on other sites More sharing options...

He said 412 CVX designed the box. 412 CVX is pretty good about designing to specs of the woofer. Unless OP altered specs or asked for bigger box? I firmly believe it should be within range.

412 CVX Posted July 12, 2012 Report Share Posted July 12, 2012 I don't remember much about this one, since it was done a while ago, but i'm pretty sure i didn't do more than 1.75 cubes net. In fact i'm pretty sure that it was between 1.5-1.75 cubes net. I could see the sub folding from back pressure, but I don't see how a puncture wound would show up in just that one spot. i'd imagine the cone of a subwoofer is pretty uniform in strength all the way around. Quote Just say no to Ground Pounder Customs. My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

I can't remember what coil he has on the sub, but with the 3.5k on 1 level 5 12, i would want to be around 1.25 net. I know .25-.5 doesn't sound like alot, but in this case it really is.

Chode69 Posted July 12, 2012 Report Share Posted July 12, 2012 did you break it in at all? if not then that can happen to cones when the suspension is too stiff and it causes the cone to fold like that...that or over excursion and unloading Quote NoFearX18 said: Nick will bang just about anything.....LMAO....pun intended On 4/13/2010 at 9:51 AM, meade916 said: i was like DAMN, Chode is hardcore! he makes james look like a friendly person LOL! trainman0978 said: I dont know who is worse with the buttholes Chode or Big P...
