I'd suggest you try contacting Richard Vandersteen. Richard does not suffer fools lightly (no insult intended) and he can be abrupt, so first make doubly sure that they are connected as described in the manual. I assume you know that they require their own special crossover inserted between the pre-amp and the power amp and that they are driven off the main amplifier speaker outputs. This is unique in the industry and is said to contribute to their ability to blend well w a variety of amplifiers and speakers.
Subwoofers hum - Vandersteen 2wq - can't stop it
I have two Vandersteen 2wq subs. Each of them hums through the drivers (not from the amplifier plate). The hum does not sound like 60 cycle hum... it is more like a buzz maybe in the hundreds of hertz range.
The buzz is audible even from 6-8 feet away. It is constant and happens regardless of whether the speaker cables are connected to the subs or not. So with the subs plugged in and no other connections made, they hum. With everything connected, they hum the same way. Also, each sub is plugged into different AC lines... one into the same line as the other outlets in the room (including dimmer switches), and the other into my dedicated 20 amp AC line with the rest of my audio system. I can unplug one sub or the other and it has no effect on the one still plugged in.
I won't bother giving details of the rest of my system since it seems not to matter. Is something wrong with my AC?
