    Got this new back in March 2002, never drove it too hard nor too loud
    but now when it's trying to work you hear several hard thunking noises
    coming from the sub instead of the regular bass sounds.

    I cracked it open but nothing looked obvious out of order

    Anyone else have this happen? if so, what was the cure?
    Thanks,
    G2

    maybe a bad cable, or cable not plugged in all the way !?

    If it is a driver problem then nothing will look out of place. With the sub unplugged from the power, gently press down on the center of the cone. Listen for scraping and scratching. A working driver will move freely without noise.

    Cables were plugged in

    And Robert, just tried moving the cone, moved without any scraping
    noise, so it must be in the amp, sending it in today, they said they
    have a fast turn around time, a flat fee of $235 for the repair and return
    shipping, a bit of a bite, had this about 7 years to the day, it's a solid
    sub, when it's working, so I'll get her fixed and go on.

    Thanks for your replies guys,
    G2
