- From the looks of your site I'd say you do like to listen to ear-bleeding
- sound levels, no? Simple test could be to swing the balance back and forth
- and see if there is a difference. If both are blown, well, you know. If
- your B&W speakers have cone tweeters (I don't know), they might make
- grinding, raspy sound as the voice coil scrapes the housing inside the
- speaker itself. Dome type speakers might do the same. Planar speakers
- are easy -- look for burnt metal 'peeling off the walls.' If you do
- find one speaker acting strange, make sure you switch left and right
- channels from the amp and see if the problem goes to the other speaker.
- I've got a weak left channel on my amp that was easily diagnosed this
- way. On a humorous note, I had a cousin who for fun (must not have
- had anything better to do) would hook up small television speakers he
- had removed from junked TVs to his monster amp. After the volume was
- turned up all the way, he would rub the stylus with his finger. A voice
- coil would instantaniously be bouncing around the room. Great fun!
