Thank you Alan and every one else who responded. This should not be a problem going forward since I will not be turning up the dial on the sub that high again. I do have to say that when I did this it produced almost "wall shattering" bass. I liked it. I liked it a lot. If I wanted to be able to reproduce this safely I guess that means upgrading to the ep500.... or perhaps the 600 or 800....
