The best sounding tweeters in the world

Well, I am biased. I own an Acapella Ion TW-1S, so I have to say Acapella :) But honestly, I think the Lansche is better.

I have also heard those MBL's. The most relaxing sound I have ever heard, they just make you want to sit back and listen to music.

My absolute favorite is the Lansche plasma.

I was listening to the plasma tweeter on You Tube and it sounds wonderful. I was also reading about it and apparently it uses an electric arc to modulate the air to produce sound, so there is no tweeter diaphragm. I wonder if air temperature or humidity affect the sound?

Not really. I suppose I could experiment with mine - take a frequency sweep, then humidify the room and take another sweep.

I heard long ago about plasma speakers. In principle, they would be ideal, given there is no mass to move at all (except the air itself).
My concern with a device that ionizes the surrounding air comes from, like storm rays can produce, in a smaller escale, not negligible amounts of ozone, what can be dangerous inside a living room.
Am I wrong about this matter?

The deal-killer for me on plasma tweeters is the known finite life. Periodic replacement is required.

Don't worry, the amount of ozone produced is negligible. You can barely smell it even with your nose right up to the tweeter.

Periodic replacement of the ELECTRODE only, not the whole tweeter unit :) $900 per pair.

Thank you, Keith.
One more thing I ignored about this very unusual type of tweeter.
Since I haven't had yet the opportunity of hearing one, I just suppose the sound must be great, based only in the intutive notion, as I posted before, that parts with mass are eliminated.

On Lansche Speakers the Corona tweeter covers a wider frequency range than most tweeters. This provides a very liquid midrange. To me, it is like the speakers don't have any mid/high drivers. They disappear to an extent I have not "not" heard on other speakers. Double "not" is intentional.

The Acapella ION plasma tweeter is probably the best one I've heard, although it is so fast it makes it extremely difficoult (almost impossible) to blend smoothly with the rest of the drivers.

The Raal one is also great, although as you have noticed - in all around performance the Magico M-Pro tweeter may be the best compromise.

Salient observations Adam. As Mike recounted, there are several tweeters which could be considered amongst the best in isolation, but not as part of a complete loudspeaker design. For example, I heard my friend's Acapella Violins and was very impressed by the Ion plasma tweeter which was very fast, but I thought there was a discontinuity with the horn-loaded midrange & bass in particular.

I've only heard the M3's once while they were breaking in, but the performance of the M3's tweeter was eye opening. They were unflappable at any volume level, fast, resolving, natural (more natural than the S Mk2 tweeters) & had excellent dispersion and off-axis performance, making room placement easier. Great tweeters!

Thanks to the magic of DSP and several drivers and amplifier upgrades, the discontinuity is now gone :)

Nice work Keith. The development of those speakers has been an odyssey to say the least! I need to catch up with you after NY & get up to date on your system development. By then, I should have a good handle on how the S5 Mk2's are sounding in my room as a reference :audiophile:.

Wow!
What amazing specs! Those monsters, apart of sounding great, must be really ease to drive.
A delicatessen for amps and ears! [emoji2]

Dizzie, hi again.
After reading a. wayne observation, and assuming the frequency range spec is correct (I'm not surprised for the higher point in this type of speaker, but for the lower), I've been thinking about a potential trouble.
I guess 1500 Hz is a problematic frequency in order to match the Lansche Corona with the unit/s covering the lower frequencies all the way down.
I say this 'cause the crossover must work precisely in the region our ears are more sensible (the always present Fletcher-Mundson curves!) and where statistically falls most of musical information.
Is this a limitation for a full-range loudspeaker system which would include the Corona, and what kind of drivers matches better with a so remarkable "tweeter"?
