Micah, I just realized what the problem is, you have an Emotiva amp running with M80s, with those 2 items working together the Audio Gods are forced to condem something else in your system and they have chosen the subwoofer. ;\) \:\)

So when are you going to modify your subwoofer space to handle dual F112's? \:\)
