beryllium vs diamond

I so enjoy "the older material" Skaaning midrange drivers used in my loudspeakers. I suspect (with tongue firmly in cheek) the implementation must overcome their polypropylene pedigree.

Keeping to topic, my loudspeakers implement Accuton diamond tweeters (BD30). Years back I owned loudspeakers using the Accuton BD20. To me, the Accuton diamond membrane sonic character doesn't stand out in the sense of immediately calling attention to itself in a "oh, wow!" kind of way. Given the cost, my initial expectation was that it would. It's positive attributes are, really, quite subtle. It is as if the treble content of music simply flows. Complex treble content from multiple instruments retains the separateness of the individual instruments to an extent I've not heard with ceramic, ribbon, or soft dome tweeters. Clarity of ceramic and ribbons, but with an ease that is hard to describe.

I've never heard loudspeakers with beryllium tweeters, so cannot offer an opinion on similarities/differences versus diamond membrane.

My brothers now retired Bozak B313's had dual paper tweeters strapped over the 12" woofers...they were sweet and sexy and full of realistic treble. Application and execution matter more, plus they had massive magnet structures behind them. The crossover was all discrete components and weighed about 15lbs.

I love the Be drivers in the Paradigm sig s8 v2 but I kind of want to move away from it since I worry if it blows 1 day the Be will become a dust in the air.

Anyone like tweeters other than Be or ribbons ?

When tweeters “blow”, its their voice coil that fries to an open circuit. Never seen any tweeter explode.
