Hi guys
I'm working on a three way and I'm gonna use a tweeter +2.5khz over an 8" midrange. I have to candidates for tweeter but I'm in maze so I want to hear your ideas please. the overall sensitivity of speaker will be around 96db. cost is no object
option#1: Faital Pro HF108 compression driver
option#2: Aurum Cantus G1 Ribbon

Faital with a Beyma horn http://www.beyma.com/getpdf.php?pid=TD-194.
The Faital has 1.3k as its lowest rec. crossover so you can cross it to match the directivity of your woofer with an 8" that would be around 1.7k.

It uses a Beyma ribbon and an Acoustic Elegance woofer.

If you really, really, really plan to use a 2.5Khz crossover with a 96db/W 8" midrange, then:
Ribbon = exceptional detail + excellent dynamics + wide horizontal polar pattern at the crossover frequency.
Compression Driver = exceptional dynamics + excellent details + controlled polar pattern at the crossover frequency.
1) For "delicate cone" fullrange, you can time-align the ribbon to the 8" by using a deep cut into the baffle(double baffle) large enough for a loose beveled felt " absorpton waveguide" glued to the ribbon faceplate. If you angle cut a felt block around the ribbon, it can absorb and also shape the exit sound closer to the beaming pattern of the 8" at the crossover frequency.
2) if you want a smooth continuous controlled directivity pattern you will need a horn/waveguide with about 60h*40v control and a 0.75" compression driver which provides great detail up to 20Khz. like ME7 from BC speakers

BAIL-OUT IDEA: The new SATORI TW29RN dome tweeter has 96db sensitivity.

thanks
HF108 with STH100 horn seems better for controlled directivity.
does anyone know if Aurum Cantus G1 could be used as a dipole tweeter? I know some of AMT or Ribbons have symmetrical front and rear but I G1 doesn't look like this
I'm answering my own question as I have my hands on G1 now. G1 is not symmetrical and could not be used and a dipole tweeter but it sounds damn good
Oh dudes it's truly a hi-end ribbon I'm just amazed how good and detailed and musical and involving it sounds
As long as you don't mind a beamy top end. I prefer the OEM RAAL to the TPL150H, except in high power/high efficiency builds.
From what I researched, TPL150H is still the king among all ribbon/AMT, but nobody's perfect I guess.
TPL-150 is IMO king of ATMs so far. I yet have to hear TPL-200. TPL is the biggest and heaviest AMT I ever seen
Aurum Cantus AST25120 is also very good.
I have not heard Mundorf stuff
