I gre out of Be Tweeters

i gave up on the etch a sketch.....

and truth be told trying to get all 4 ESL and decca ribbons to work together.....let alone the Hartley subs...
the big Infinity had similar issues with woofer tower placement..argh...

In thinking about your answers, and my own experience, I have to restate my original post.
There are tweeters sporting a wide range of technology I like, including Be, but the sound I heard from the first, micro-motor Be tweeters is something I have completely outgrown.


I was entranced by the waterfall plots, which are very very good for Be, but ignored that what I was hearing was also the metal dome character of them. Something several modern Be tweeters have overcome.

I also realized, after posting, that there's some technology which I may like some examples of and not others. AMT tweeters for instance, share an almost mythical story, and can be had from $5 each to $500 or more each. They are by no means the same, and I've heard some speakers with them I liked and some I truly could not listen to.

I never cared for porters until one day in Winthrop tried their Bulls Tooth Porter. Freaking amazing. Turned friends onto it, they all loved it too. Even people who never liked dark beer. And this was VERY dark beer! But awesome!

Spent pretty much my whole life looking down on lagers. Anything light, really. Even as a teen, never cared for em. Till one day, Scuttlebutt Trippel Seven. Pretty darn light, yet somehow rich and creamy and full-bodied. Wish the Bulls Tooth was still around but at least we still have the Trippel Seven.

Not sure what this is good for other than to expend a few more milliwatts and eat up a few more bits on the interwebs, but what you said about technology, what you're talking about is the difference between technology or design and implementation, the particular details of how the technology or design is brought to fruition.

Rear engine technology for example is such an awful approach no one does it any more. Except Porsche, who somehow has managed to make the worst design into the best car in the world, a fact they have proven again and again for an incredible 60 years now. 

I may not like Bose products, but no one on earth spends more both on speaker analysis and marketing analysis than they do.

Like them or not, they are a model of having an engineering arm tightly coupled to consumer preference and experience.

I doubt if you can tell one decent tweeter from another if they are competently implemented.  Most audiophiles just can’t stand not changing things.
