Definitive Audio Players & Recorders - Recent Questions, Troubleshooting & Support
My Definitive Technology Supercube ii
Unfortunately, the most common problem with powered sub woofers, including definitive technology, is that the capacitors inside dry out. To check the speaker, you can connect any line level audio source (like an mp3 player) to the speaker and see if it comes on. If it does come on, then you will know the speaker is ok. If not, then the speaker will need servicing. Powered sub woofers are not usually a DIY project.

My definitive technology pro cinema 600 sub stopped working
theres a setting is on the subwoofer itself, not the AVR. It usually has 3 positions: On, Auto, Off. Auto allows the sub to "sleep" when it's not being used, and to power back up fully when it senses a signal. Maybe change to On position which would bypass that auto mode
Pro sub just shut down no red signal light dead
start at the basics, check home circut breaker box, ensure it is still plugged in, check the fuse subwoofer itself. unplug and disassemble, to ensure no moisture or a fried bug is the sorce of the problem, ensure the leads to the subwoofer havent popped off or become crossed, etc etc. hope this helps
