I used to own the Velodyne HGS-18II and it was dead quiet. Maybe you could upgrade yours to the Series II? I now have a DD-15 and it's very quiet.
Velodyne HGS-18 "whine"
My Velodyne hgs-18 has developed a high-pitched "whine" whenever powered on. I remember reading somewhere in the past that this is a problem commom to this model. Has anybody had a similar problem with this model sub and had it corrected? You can't hear it when the music is playing over it but when the room is silent you can hear it from at least 9 feet away.
Thanks.
Thanks.
