for those that didn't know, one of my subs stopped working, so I yanked her apart, and saw a very devistating site... the cone had been sheered off from the magnet.... not torn, sheered. I thought back to what could've caused this and then it hit me... my roommate threw a bowling ball in my trunk when we went to the bowling alley, and didn't tell me about it, so I had my subs on.... well... a 1.2 Kg magnet thrusting a cone into a 12 pound bowling ball would break something.. and I"m assuming it broke the paperish cone. My theory anyway... I'm in the process of attempting to fix it with superglue... I'll have to tell you how that turns out.
