The dead Class D

[Daryll]

Following on from another thread.

One of my Class D cd15 bins has died ( I think).

So I get the thing home , plug in a suitable source , and nothing , next ( on advise) I remove the speakon plate and both handles , all wiring seems ok , to my surprise , putting a battery across the driver terminals made the cone go in or out , depending which way the battery was connected , the last component was the crossover , looks ok ,however putting the battery across the input to the crossover gave a direct short , by the way the crossover was sending a signal to the top cab last night , any ideas people ??

Cheers

Sounds awfully like a dead crossover. Have you tried swapping them over, or feeding the driver directly with a signal? Without being a smartbottom, it's better to use an active crossover.

Does the crossover have a fuse or 'light bulb' protection curcuit? I would replace if they do if not call class D for a replacement.
