High Efficiency Tweeter that can cross to a 8 inch mid
As the title says looking for a High Efficiency tweeter (with a good top end) that can cross to a 8" mid. Need 95+ efficiency. What I could identify:
Satori Neo (dimple dome or BE)
RAAL 140-15D (how low can this go?)
TL BE dome
Mundorf big AMTs (e.g. AMT29 or 164) good horizontal dispersion, but very narrow vertical
Blisma T34 - very new and very interesting
Not listing the Beyma as it's top end droops off
Cost wise, it's only the Satori that has a decent performance and high sensitivity, everything else is uber expensive. The Mundorf's seems to have the most power handling and good blend of sensitivity and top end coverage, though the vertical is very tight.
Any inputs on how these sounds and if they can be crossed low (1800 would be ideal, can maybe push it up to 2k)?
Also open on the mid, 95+ db efficiency, need not play low, but should have good power handling, not set on 8", but this looked like the best compromise, 8 ohm is preferred which rules out 2x 6" mids. The top runner is the 8" AE mid, but not sure how long it will take to get it.

Tweeters are subject to Hoffman's Iron Law much as woofers are. To refresh, Hoffman says there is box size, LF extension, and sensitivity - pick any two of those three, the third will be a compromise, usually severely so.
This unicorn tweeter you are chasing after probably does not exist, as you are no doubt discovering, virtually every tweeter that will legitimately play at 95db/w/m is limited on either the LF (hi-fi tweeters) or HF extension (PA tweeters). This is why horn loading compression drivers comes into play (basically making it 'bigger', if you will). Generally though, in order to match directivity of large midwoofers they sacrifice the top octave. However, you can easily get a horn loaded driver to hit a true 100db sensitivity level from, say 1K to 10K.
There are some good resources out there on how to design what amounts to a PA speaker, Ani. I highly doubt you will hit your goals by shopping traditional "hi-fi" drivers and design concepts.
Plenty of flat face plate tweeters to choose from.
The closest you'll find is likely the DX25 and it's variants. The sensitivity is almost there.

DE250 will meet your needs, as well as most other decent compression drivers. An lower cost option could be Tymphany DFM-2535R00-08.
Solen recently had these on sale at a decent price . Im not sure it has the dispersion youre looking for that the domes would have though.
The RT2C-A will play to about 2.2-2.3k, and it is REALLY sensitive, and REALLY LARGE.
