I have an older HGS-15 (bought it 12/2000 from Sound Advice); it's been flawless for years, but about 2 years ago, it started developing a problem. Essentially, a very loud hum would come over the line and it became pretty much useless after that. I plugged in a smaller sub, and everything worked fine, therefore leaving the HGS-15 as the problem. I tried to contact Velodyne, but no-one ever replied to my email, so I essentially gave up. Today, I decided to try again, and found this support forum. Can this sub still be re-paired? I suspect it's the PCB, but just a guess since I haven't messed with it in about a year (when it went out).
