Here's the deal.
Last Saturday night, set up everything, sound checked fine and then hooked up my Starball, which I rested on top of my FBT sub.
I tested that and it worked fine, but (coincidence?) suddenly the 12" FBT powered speaker on a speaker stand behind the sub starts acting funny.
A bizarre white noise could be heard, just from that one speaker. The one on the other side worked fine as did the sub.
Here's the twist...if I rotated the speaker a bit on the stand, the noise would fade (but not completely go away.) After a moment, the noise would get louder until I rotated the speaker, and then it got softer again.
It was noticeable on soft volume, but when I turned up the volume for dancing, the white noise did not get louder. The music then drowned it out the rest of the night.
I haven't had a chance to check things back here, but I figure it was either a fluke thing, or a problem with the output from the sub. Keep in mind that only one speaker acted up, not both. I even tried using different cables to connect to the power and mixer out, but the noise remained.
Anyone have an idea as to what's going on?
