This sub was working fine till recently.It would shake the walls & sounded great for movies.Now it seems to have lost it's oomph.It no longer can shake the walls but kind of sounds like it is cutting in & out.Playing with the settings does nothing to help.Could something be blown ?Any advice would be appreciated.Mike
