disprovable

Damn. The guy who designed it kept saying they like 1.5 cu each and was trying to make a box that was 3 cu after all displacement..

Really for 2 level 3 10s that's too big? Dc recommends 1 cu Ft each

It's tuned to 32 hz and after all displacements about 2.4 cubic feet

No i did not. Here is a link to all the possible specs of the box. http://s1357.photobucket.com/user/Dylan_Sawatzky/slideshow/Box%20Specs

Well, thats how the other sub started out thats what i meant by the surround had a weak point. It started like that and then bad down spiral. It is pretty hot in oklahoma, but ive never had any of my other subs separate like that.

And this is my other subwoofer. Haven't looked at it but it looks like it's doing the same thing as well.

This is a spot on the opposite side of that subwoofer that appears to be doing the same thing.

Im very unlucky apparently. I got a defective crescendo amp as well. Showed the pos and neg connections as reveresed and that blew a link of fuses at my battery that are needed for my car to start. 50$ for the fuse block.

Yes it has. There are pieces of the surround all over my trunk.

No i did not spray any cleaner, the sub was installed and left alone ever since

There's pieces of the surround all over the trunk but other than that its just my subs and the box and amp in my trunk.

This is the sub as it sits today. Haven't touched it since just let it do its own thing

It almost looks like it....did someone break into your car?No one broke into my car just one day I noticed the sub looked somewhat weaker in that area and over time it caused that to happen it didn't all happen in one go yeaaaaaahhh... It definitely happened on its own. I was not digging for a recone. I actually went online and purchased a recone kit from droppin hz. It was not punctured with a drill. Car was not broken into. Was not punched through. Literally opened the trunk to see that. Swear on god, my life, whatever. I was just posting a picture trying to get opinions on what it could have been. It pisses me off that you jump straight to user error. I had the sub for a few days before that happened. It is still hitting, and has slowly gotten worse over time. I haven't had any luck with subwoofers in my experience. Check my old topics. I also received an apparently 1 and only defective crescendo amp.

I'm just not sure what initially caused the surround to weaken
