I have a Celestion 8in 100watt home theater sub thats making a funny continuous disorted sound. I believe it's coming from the phaze adjust. I used to be able to turn it 180* and the sound would go away, but now it's back. I'm thinking maybe a connnection is bad, but I have noo idea.. It's really annoying to have on...I can hear it all the time, so I finally just unplugged until I get it fixed. Any ideas what it might be, and what it would take to fix it, if it's even worth it? Thanks!
