I woke up in the morning a couple of days ago and I heard a loud humming noise coming from the basement I thought it was the dehumidifier but when I went to check it out it was one of my subwoofers from my hometheater. I thought it was something going on the the connection but after further study it was just my subwoofer. I took it out of the setup and began working on it. every time I turned it on it would start humming. I checked the fuse but that wasn't it. I took out the speaker and man did it stink like burning metal. It was the driver itself that smelled burned. I hook the driver directly to my upstairs system. The sound was fuzzy but it produced actually sound not a humming noise. I hooked up a passive subwoofer up to the subwoofer amp and there was the humming noise. I'm sure it's dead but am not sure what's the actual problem. Have you guys ever heard of anything like this. It's not too much of a problem since it's was used for secondary purposes. and I have a few others to use. I guess that I will be throwing the amp and the driver away. One thing however, I am shocked by the sturdiness of the enclosure. It was my first ever power sub and was at least six or seven years old. It wasn't terribly expensive so I did not expect the build quality to be this decent. It was even braced inside and have dampening matierial inside. I was messing around once with a subwoofer from htib setup and when I took it apart it looked everybit of it's price. Anyway I can't bring myself to get rid of the enclosure, I'm not sure what I'll do with it I will figure something right. Have ever lost a sub if so how did you dispose of it.
