Calling Vandersteen Subwoofer Users

Greetings Bonmapp
you dont need to borrow a duet
just plug everything into even a cheap hedgeclipper extension cord with a few extra outlets to be on the same phase leg.......... Try a basic ground wire from pre amp chassis ground to Subs ground lug
Ig316b are you sure you havent been ordering from web jockies? sorry to be the messenger again
Grados and VPIs also hum together.

Thanks John. That I can manage! Will try it soon and report back.

John Thank You for the advise.
Sorry to have taken so long to report back, got a little busy over the past two weeks. Was able to get all the testing done and the 2Wq's are still humming. Good news is the Grado/VPI are not the source, with it completely disconnected (power and interconnects), the hum is still there. Tried connecting everything to the same phase leg, with and without a ground wire and the hum seemed to get worse, the ground wire didn't help at all. Disconnected all components to see if any were causing the problem, found a worse ground loop when the AVR was connected, was able to correct that but with the AVR disconnected the front speakers were dead quite, connected the 2Wq's and the subs started to hum. Funny part is they are not as loud up close as they are when the two combine between the speakers. Good thing is you can't hear it while the music is playing. Guess this is something I'll have to live for a little bit. Anyone have any more suggestions.

If you have a cable box in your system disconnect it. That's where I've found my problems before.

AVR? 2WQs
what brand? and do you have Pre amp out and main In?
Bhaaf good advise disconnect the CATV as well
