Just today I was listening to my system when I began to notice a very audible (and annoying) click coming from my center speaker (something leads me to believe the tweeter). It happens on multiple sources (HD sat and DVD). It's not obnoxiously loud, but is distracting enough to detract from watching a movie. It seems to be random, with no real pattern to the clicking. My center speaker is a Definitive Technology LCR2300 and my reciever is an Onkyo TX-DS797. What is wrong with my system, and more importantly, how can I fix it? The entire system is less than a year old, and has worked flawlessly until now. If it matters, the Onkyo is also driving a pair of Def Tech BP2006TL's and a pair of Def Tech BP2X's.
