    If you pick it up and physically shake it, does it rattle?

    What sub have you got, and how have you connected it?

    Has it always done this, or just recently?

    Are you sure you havent blown the driver??

    My cousin has just blown his Kef THX sub and he wasnt playing at reference level either.

    Or maybe the drivers worked itself loose?? I´d take it back to your dealer and get them to send it back to Kef.

    My previous sub was a Polkaudio PSW-50 which started to make a rattling sound during high volume action sequences. I took it back to the supplier. The spider had come undone from the cone due to a manufacturing defect where the glue did not set properly. As a result, the voice coil was misaligned and scraping on the magnet causing the rattling sound. My sub was out of warranty but the supplier managed to arrange a replacement driver free of charge.
    Maybe you need to check if you don't have this problem by removing the grill and pushing gently down onto the driver with two fingers and listening for a scraping or scratching sound.

    The sound you're hearing is either the voice coil bottoming or the amp being driven into 'hard clipping'. Neither is healthy for the equipment so you might what to turn it down...
