Sub sounds like a helicopter (very unusual behaviour)

    Hi everyone :) Just stumbled on these forums, can't believe I hadn't found them before!

    I have just been demoing a Kef PSW 2500 Sub from the local hi-fi shop. While the guy swears it was working in the store, plugging it in at my house resulted in nothing more than a "Whop whop whop whop" sound, like a helicopter. The sub wouldn't power on properly, and the power light was flashing. While he's returned to the shop to get a different unit, I'm worried that it could be a problem with my mains power supply. Does anyone have any experience with this behaviour?

    The hi-fi guy said he had never had that happen before!
