I have a set of .BeoLab 8000 speakers that has no sound.  I have checked for foam rot  and did not see any.  it appears that all woofer drives a on of the treble is out.  There is no ohm value (open) when checked.  Took a look at drives and there was no magnet wires connected to studs.  Plus 2 of the cones were torn.  I connected a cheap Radio Shack speaker to pins of P6 terminal on board 2 and there was sound.  My question is before I buy new drives and install them what can or should I check to insure that I don't blow these drives.  Also, is there anyway to repair the drives or is it best to to buy new?  These units were given to me this way so I don't know what happened.  Any advice would be greatly appreciated.

Thanks,

gary

Hi,

 

I suggest buy new speaker. and to ensure  it will not blown the new one. make a  dc measurement in the  output  make sure no dc out put using multi tester  in normal circuit  there is no dc output in the main amplifier output. it should only be  a/c  signal.  and to ensure the amp. is still in good condition make a resistance test for a leakage in the circuit.
