This is a bit silly question... how is polarity of T27 and T52 marked on Kef Tweeters. Is blue wire negative or positive terminal?

Are other drivers like B139, B110 etc marked with red for positive as usually.

Best Regards

Unless my memory is playing trick on me again then it is the Blue wire which is the +.
Yes, on the other drivers the + is Red.

Yep, my T52 and T27 were blue +
Maybe a red wire on the T27 would have been too visible through a thin grill cloth?

If you're puzzled by +ve blue, it's because blue light is a higher frequency than red light. Hence black is always negative. Blue is for tweeters, green for midrange and red for woofers.
