Beryllium Tweeters

Listen to some Focal speakers. The Chorus or Ariel Lines have speakers in that price range. They have a different tweeter material, but I think you would appreciate them.

You could look for a pair of 2nd hand classic Yamaha NS-2000 speakers which use a Beryllium tweeter. I'm feeding a bit higher up the food chain & own a pair of Magico S5's which employ an excellent Beryllium dome.

I think the beryllium tweeter is nice as I had owned a pair of Paradigm Signature S2's V3 but found them too bright at loud levels. Sometimes harsh sounding. I was even running them with a hybrid tube integrated which smoothened things out a little but still not to my liking. Not for everyone. I switched to custom horns( Casta Acoustics model D8's). Love them. No harshness. Extremely clean, phase coherent, smooth midrange dynamic and fast.

I own Paradigm Signature 8s (v3). Yes ... they can sound bright, but I wonder how much is the fault of the source material. I say this because my new "tweak," a DEQX PreMATE tamed my S8s. They are now more time coherent and room EQ'd. Even still, some source material is "bright'ish" to me. I attribute this more to the source material than the Be tweeters. Presumably, as a result of the DEQX adjustments, my speakers should have a pretty flat FR.
