    Ok, my cab seems to have this nasty vibrating/buzzing when I play certain notes (A, D) Every other note sounds fine. It gets worse when I play the higher octave A and D notes. I don't know what it is, it seems like something might be loose inside and those particular frequencies are causing it to vibrate? Any ideas on what could be wrong/what I should do? :mad:

    Did you have a hermit crab or hamster that got lost in the house recently??Kidding
    Go over it with a screwdriver if you havn't already..make sure ever screw and bolt is snug. If all the screws are snug you may need open it up and see what's going on, but if its a combo and theres an amp in there you may want to take it in, unless you have experience be carefull...also tell us what kind of cab it is..

    Tighten all the screws and bolts on the cabinet and speaker mounts.

    While the Grill is off for tightening speaker mounts, check
    the speakers for Voice Coil Rub by placing clean,dry
    hands at the 9 & 3 position and gently/evenly press the cone inward.
    Listen and feel for rubbing (zipper like).
    The cones should 'bounce' with no resistance whatsoever.
    If there is a faint 'saw-like' sound, could be voice coil problems.
