The Problem Oh dear, last week I had an incident with a dodgy lamp sending a load of static through my speakers which I thought may have damaged them although they sounded fine. About a week later I was watching the 51st State on DVD and during a loud explosion (sounded v deep) the right speaker produced some crackling. Everytime I played the scene the right would crackle. This is where things start to get wierd, I tried listening to the scene with headphones, no crackling, I then tried again with the speakers and it had gone, no crackling atall. Thought all was well until I have heard a few more strange things; 1. Random (very infrequent, once every 5 days or so) pops from the right speaker during very quiet, almost silent scenes when watching tv, not on DVD or music. 2. A bassy rumble in a film on tv caused audible crackling from the right speaker. What I have tried I have listened to many dvds, music etc and I can't hear anything out of the norm. Ran test tones at low-med volume from around 40Hz up to about 10kHz, no crackling. Pushing gently on the bass driver doesn't feel rough or makes any noise. Binding posts on speakers are tight Possible Causes Recently moved the unit that the equipment sits on which moved all the wiring. Any suggestions, I am at a total loss. Many Thanks Dom.
