I think it`s my center channel that`s bottoming out on a specific spot in the Haunting DVD. I`ve played it many times but did`nt realize what was going on. It sounds like a loud clapping sound. How many times can you bottom out a speaker untill it`s shot? Please don`t tell me it`s too late. I think it`s the center but not positive. Paradigm Studio CC with 100wpc Onkyo receiver. Is there a way to tell if its ruined?
