With no luck of sourcing a fresh Beolab 1 tweeter i experimented with a fresh Beolab 6000 tweeter.

While the exact geometry of  Beolab 6000 does not fit in the contour of the column it does work.

Can I please make a request to advise me on the following:

1. whether the above "jugaad" (indian term quick fix) is advisable given there is difference in the impedence (marginal though)
2. is it  likely cause any damage to the chasis - given the impedence varies between the two.- does it involve changing the values in the potentiometer
3. what are the exact impedence of beolab 6000, 8000 and beolab 1 tweeters
4. above all can i still be hopeful of sourcing a fresh Beolab 1 tweeter

Thanks very much indeed for your kind patience and look forward to collective feedback/suggestion.

Cheers

continuing with my experiments with Beolab 1 . given the unavailability of spares i tried to recone the tweeters locally here. even that would repeatedly fail.

finally i tried my luck with a brand new 7-1 tweeter. with the impedence closing matching ~ 7 ohms i replaced it with the original tweeters and the speakers came to life. both my units currently have 7-1 tweeter.

while the screw holes do not exactly match with the orginal i made a temporary "jugaad" to secure them in the slot.

let me know if the choice of 7-1 is a good idea. 

cheers
