Grant...correct me if I'm wrong, but that photo looks like some of the new JL Audio stuff? Is it the marine grade stuff that is supposed to come out this summer? I've been looking for it, but I've been told it is not available yet.
It was a Dayton 10" in my car running when it self destructed. There are several burn marks on the voice coil. I think it overheated and the glue holding the VC together let go. It over extended itself and stuck there. You can see where the paper cone was started to fold from over excursion. It's rated at 200 watts I was pushing 400 through it and wondering how long it would last.
I have another Alpine 12 on the shelf when I get a chance to open up the mounting surface of the box.
