I agree with everything but the last paragraph.Um, how is the Focal Be the best among them? It has a miniaturized motor and ragged FR with high amounts of compression. The medium grade (among Be tweeters) ScanSpeak Illuminator D3004/6040-00 spanks it and it's dad.
The SB Acoustics has yet to be released, but the published, preliminary FR is among the best I've seen.
The Mundorf AMT's spank all of them...... << runs to get popcorn >>
Could not have put it better myself.to date I've seen no real proof that any beryllium usage, either pure or heavily alloyed with other materials, is any better than aluminum or coated fabric. There's certainly a lot more to a tweeter than the chosen diaphragm material.
That's because he didn't test a Be tweeter, welcome to 2007: https://www.google.com/url?q=https:...mJHhgw&usg=AFQjCNGlXSE3m5_nwQx-Oc49JsWw2hy-4AZaph once tested the Beryllium version of the Usher 9950/Dayton RS28. Performs identical to the aluminium dome version. His comments:
Could not have put it better myself.
Asking what the best beryllium dome tweeter is, is synonymous with asking what the best metal dome tweeter is.
The N26MG is closer to the N28BE due to its higher SPL level (94db) and very light moving mass.
However, the N26CS has a better sound quality compared to the N26MG.
If your trying to stay close to the N28BE, I would say the N26MG would be the best choice. However in my opinion the N26CS is a better sounding tweeter due to its very smooth while detailed sound quality.
The N26CF is a very different tweeter than the N28BE and would not be a close to the sound character of the N28BE.
1.4khz with a 48db slope is ok for these tweeters , it just depends on how loud you plan to play them.

for the Seas magnesium series, I also have the 22taf

I understand that I talking about the "prestige series" and you refer to the 1" version or the Excel. If the "Excel series" behave the same way, they aren't very good. On paper, I think they can compare. I bought the little 22TAF cause the HD above 2.2Khz were very good (was crossing at 2.5K then)
Zalph has measurement on his website. the Seas MG have a big breakup. despite being in 35-45Khz range, it produce harmonic that are quite audible. especially at higher SPL. headache is a consequence of listening for prolonged exposure to my 22TAF. there was also a feeling of restraint when listening, triangle and cymbal seemed to extend longer than they should, it was noticeable and once you knew it, you heard it all the time...
Thanks Scott, I didn't realise Xmax meant "linear." The numbers are so far different from one another, with tweets otherwise similar, that I knew they could not be the same.
Actualy, I think Seas makes a Be tweeter too, don't they? It would also need a little work as it's a camel-shaped response, but I'd love to get to listen to it.
