JL Audio f112 blown speaker?

I have/had a JL Audio f112 and I absolutely love it. About 3 months ago I changed my processor from a B&K Ref 50 to the new Classe SSP800.

About a month later my f112 started, for lack of a better term, started screeching, when I would play it. I have no idea what happend, but I unhooked the XLR connection and it would continue sporatically, even without any signal.

JL Audio was absolutely great. I sent it in and 5 days later a new one shows up at my door. Now after a month the same thing has happened with my new one.

I'm not playing them loud at all. I play video games, watch movies and listen to a lot of music.

Something is up and I am clueless what it is. It must be something in my system causing this. Any suggestions?

Rshad000, Hope all is well now. I just love the musicality of the F113's. Really changed my thinking on subwoofers so I will be getting another soon. Nice to know that JL Audio stands behind there product and takes care of people in a timely manner. Things like this do happen in audio and I have heard of some horror stories besides mine. I am also glad I don't hear this compression. This would make for an unpleasant experience and a return to vendor journey. HT Shack highly recommends the JL Audio subs. The JL is one of the best they have ever heard from what I read. I highly encourage people to read what the tester wrote on at least the F113. Can't say I really looked into the F112.

I turned up the F113 to levels I would never play normally and watched this excursion. Maybe 1" of excursion outward was noticed. To push this any further is not normal. At least for music. Movies may be a different story and I have had it loud enough to make it feel like my couch was being lifted. With one of these in a room 18' wide 40' deep and 10' high I have been extremely impressed. Two of these in this room will just work that much easier and give more depth and extension. It's going to be fun.

One would have to drive this F113 to insane levels before hearing any distortion. As an owner I can promise you this.
The testing that is being done on these subwoofers are not real world. They do show what happens on a graph which does not mean too much to me. I would much rather listen to the sub in my own listening room and try to calibrate and integrate with the mains and room. The JL Audio has great features for doing this. Do we even know what excursions were taking place when this distortion was taking place?

What I don't understand is the fact that all the reviews basically rave about this sub and yet they have this so called disortion in the way. I have tried everything in my power now to drive this F113 to the point where I should be getting distortion or cabinet resonation. I have a dedicated line and a Lessloss power cord on it right now so maybe that has something to do with the sub not distorting. I feel this sub is great for movies and outstanding for music. It controls the higher frequencies with precise accuracy ("very real musical bass")and zero localization.
