My front mains have powered subs. I just noticed the one is not playing. The amp is on, and light is green, but no sound from woofer.
I turn it off, and unplug the AC power cord, plug it back in, power on, and it will play for maybe 20-30 seconds, then stop. Sounds fine, and power stays on, not hot, can't figure it out.
Seems odd that it plays shortly, then stops, but doesn't seem like it plays long enough to be a thermal issue, and wouldn't light change from green to red or yellow if an amp or signal issue?
This speaker always had a crackling/fluttering sound occasionally when it would get a lot of bass signal, and I always felt like there was a loose connection inside.
What does this sound like?
Should I open it up and see if I can see anything?
