My hunch it will present the best all around highs,
So tweeter choices?
I have no idea,
Good luck with the search.
As for just the tweeters themselves
Magnat MP-02 Plasma is the ultimate tweeter, I have a pair nothing else approaches them, the surrounding burning gas becomes the 360 degree diaphragm. (and is as light as air)
followed by horn loaded Plasmas, then ESL’s, then Ribbon/Planer then domes.
Those plasmas look excellent. Then there is the v important issue of the crossover. And already $4500 why $600 for shipping?
It’s has an 18 or 24db per octave xover and can be adjust up from 3khz and also the level all on the back.
And yes $600 for post is very steep, but they are a solid two hand lift.
They do smell a little so I use them in summer (so I can have a slightly open window, like you do with gas heating) with the ML esl Monoliths (with replacement Neolith panels), and roll off the esl panels at 5khz and bring in the Magnet MP-02’s. Which go out flat it said to over 50khz with no problems.
They really do add even more "air", delicacy, 3d transparency and speed to the sound than just the esl’s, which is unbelievable, as that’s esl’s best traits.
No such thing as best, each design is unique.
in a AMT tweeter the Beyma is probably the best .
Accuton has the great $2k Diamond ceramic tweeters ,
Plasma tweeters are very unique and great ,but need to be recharged every4-5 years ,MBL 101 Omni directional speaker
great in that application , then custom dome tweeters that have their own attributes several very good brands ,
and some very good Ribbon tweeters . That’s my opinion .
I don’t know if one can evaluate a tweeter alone, , in isolation from other drivers in a system. There are many fine examples, that can work well in the right system, such as Magneplanar ribbons, pleated ribbons (e.g. AMT), and one of my favorites—Western Electric 597 fieldcoil compression tweeters. The 597 is particularly good at disappearing—you hardly know it is working. I heard a fantastic version of the 597 made by G.I.P. Laboratories (this tweeter costs $60,000 a pair); it is in the running for best tweeter.
There are a couple of great Beryllium tweeters. D3004/6640, TW29-B, D2908-7140, etc ... You have Raal. And more. Yet for me, I will mirror what others have posted. A good AMT just sounds very real to this 40 yr musician veteran's ears. I love some Aruum Cantus. And although I'm not a fan of Heil dipole tweeters, I love the old round face monopole AMTs! If crossed over high enough in a 3 or 4 way, they are among the best available today.
The LD50 of ozone for humans is around 50 ppm, so this is a real concern and this is why they are not made anymore.Don’t know where you get that idea, these are the newest horn loaded ones, but are little colored sounding because, of the horn and don't have a 360 degree radiating pattern
Aurum Cantus ANY of them. Biggest bang for the buck. Replacement ribbons on a lot of them. The SQ is just perfect.
Singles (toppers with enclosure) LS or as a conventional Top mount and driver below or MTMs.
12 or 18 db XO 2nd or 3rd order. DON’T squeeze on the XO, no first order cheep crap. Smoke comes to mind. :-)
Morel has some great soft domes. I just love too.
I’ve haven’t heard them all, BUT no hard dome anything.. Doesn’t matter, I’ve never been a fan.. Way to easy to beam and my ears just go bonkers.. I want to choke things.. I've seen Pro bullets cause fist fights.. Had to turn them OFF at concerts.. LOL
Well then since you're not looking at buy/add to your current speakers check out Dali Epicon Series approach use Two!
Twin tweeters are something of a Dali speciality and comprise a fairly conventional dome working together with a ribbon unitbest of both worlds approach The ribbon tweeter simply takes over where the conventional dome starts to tail off, which in this case is around 15kHz. The idea is to maintain treble dispersion at the highest frequency and, obviously, take advantage of the quality of the ribbon unit.
Result - very unique detail sound
The best speaker I have heard so far is the Lansche 8.2. It uses the Corona Plasma Tweeter, that George referred to earlier.
After Lansche's Corona Tweeter, RAAL 70-10 ribbon and ELAC 4 Pi Omnidirectional are at the top of my list.
Corona Plasma measures up to 150kHz
RAAL 70-10 Ribbon measure up to 100kHz
ELAC 4 Pi measures up to 50kHz - I use in my system.
I have never had the opportunity to hear the Magnat. From what I have read they measure in over 50kHz.
Accapella Audio Arts uses the Ion Plasma Tweeter, and sells stand alone units which both measure in at around 50kHz.
Plasma tweeters are still being produced.
