Well, I was watching the Incredibles over the weekend and my sub (20-39 PC+) made a loud cracking noise...then nothing.

. I've watched this movie before and haven't had any problems. The gain on my sub is just before 1/2, +3 on my receiver (HK AVR230) and the volume was at -34. I've only had this sub for 7 months. The power light is on too. I'm not sure what else to say that I really do miss the sub. It makes a huge difference and now I want it back..haha
I emailed tech support but I know it's still early. It's bothering me so I figured I would get someones opinion on here as to what they think is wrong with the sub.
Thanks!
Walt
