Re: How to Troubleshoot a dead Sierra-1 Speaker?
1st thing.... Remove the drivers. Simply remove the screws fastening them to the cabinet. Verify that the lead wires from the crossover are securely connected to the 2 terminals on each driver. If any are loose, reconnect and try playing the speaker. If you have sound then that's all it was. If the lead wires are all attached when you remove the driver, remove the lead wires from the terminals. Now, you can try holding the speaker wires from your Denon to the terminals and play something at low volume to see if the driver produces sound. Do this for the woofer and tweeter. If they produce sound directly connected to the speaker wires then it's probably the crossover.
Give Ascend a call and they can guide you as well.
