    Hi

    Just got my Kef THX package from the UK. Set it all up, started the test tone and the right hand driver of the right surround is making a crackling/rattling sound, BUT, it only does it with the test tone! films etc sound ok.

    I took off the cloth cover and the crackling faded away, it also comes back if you touch the driver lightly with your finger.

    Anyone got any suggestions before i give the dealer any grief??

    cheers in advance

    Both of my bass drivers buzzed due to the dust cap, (in the centre covering the magnet pole)becoming unglued. I took both of mine back for replacement. Recently it happened again - I couldn't be bothered to take it back and stuck the damn thing back myself.
    You fault could be different- could be the voice coil touching the magnet!

    Anyway - get them to replace it!

    It may be that the mid-range cone is rubbing against the housing of the Uni-Q tweeter. The tolerance is quite tight, slackening off the screw holding the tweeter in place and repositioning the tweeter will cure the problem. However, to do this you will need to unscrew the mid-range unit from the cabinet to gain access to the screw holding the Uni-Q tweeter in position.

    Before attempting this confirm it is the cone rubbing on the tweeter by applying gentle pressure to the mid-range cone with your finger to 'pull' it away from the tweeter (look closely face on to the unit to see which side of the cone is closest to the tweeter to apply the pressure).

    As they are new units I would just send them back for a replacement rather than risk invalidating your warranty.
