Darrylhifi,
The effect I heard was from moving the sub woofer SIDEWAYS, away from the Soundlab Ultimates.
Since the Soundlab is a dipole, the sub at it's side has very little effect acoustically. Anyway, I'm discussing the sound with the sub woofer (un- shielded box) in an inoperative state, merely it's presence both magnetically and electrically.
The magnetic field in the sub is strong due to the 15" woofer and even worse, the built in plate amp (200 watt) effected the power supply of the Soundlab. I assume the step up transformer or bias circuit was being effected but cannot say for certain.
Herman is correct that moving speakers have great effect sonically but in this instance the sub was definitely effecting the Soundlab, other than acoustically.
Since magnetic fields are so easily seen on televisions when speaker fields are near I don't see much stretch in imagining it could effect some circuits during music playback.
