Hi all, not sure if there's any A/V techs here?
I've inherited what looks to be a Hill Audio 15" Active Subwoofer (circa 1990's I believe) and having an issue with it.
The sub will power up and work for a short period of time but then start "buzzing" loudly. The cone looks like it get's pulled back and vibrates in that position.
I've checked all connections, different cables etc so I can rule those out.
I've attached a video below showing it working and then going to the 'broken' state.
Any ideas would be much appreciated. I will probably have to send it off but curious if it's something I could DIY.
Thanks!
