I haven't been around here in a while, 17 credits of engineering classes are keeping me pretty busy...I hope some of the helpful people are still around.
I made the mistake of hooking up an ART Cleanbox while my amp was on and turned up about 75%.  My sub made a loud pop and extended about 2 inches past the front of the sub.  I tested it out and it started making a rattling noise.  After taking it out of the box to inspect the damage this is what I found.
	
	
		
		
	
	
Forgot to mention, this is my DIY Infinity Kappa Perfect 12.  At least I have a backup Perfect 12, I meant to built 2 and just never had the time.  So can it be fixed?  Are there even parts out there since it's been discontinued for a while?  Worth the time even, is there something better out there for us DIYers?
