Faital HF146 vs HF10AK - Top End Performance

Some like the sparkle of break-up resonances.
Sometimes break-up is perceived as (artificial) spaciousness.

At higher levels the modes may start to bite and cause listening fatigue.

The break-up of the 745NEO isn't too bad, but nevertheless seems slightly worse than my old B&Cs with 3" Titanium dia (Mylar suspended).
Either way, the folks at Radian certainly know how to make a proper Aluminium diaphragm in the grand tradition of Emilar.

Here are some measurements of the hf108r on the phrn-1014. Two things to note, there is 16ohm in series with the CD, and the waveguide has 2x 3/8 inch holes drilled in it, but they are not too close to the throat. I added the midrange in one of the pictures in case anyone is interested in that too.

The angles are 0,15,30,45

Ro808, which driver you would prefer above 2000Hz - BMS 4526, Eminence N151M or Faital Pro HF10AK?
Thank you.

The HF10AK, but that one seems to work better with deeper (Salmon type of) horns.
If you like wider dispersion and constant coverage, the HF108(R) would be preferable and judging by the plots in the previous post it can be crossed pretty low.

Ro808, do you think that HF10AK or HF108(R) can be integrated in a home/room listening system with high-end ambition?

The HF10AK is one of the best sounding HF drivers around. At the price it will be very hard to beat. It has a very hi end sound to it and is better than most domes, including the Scan BE tweeters.
Just look at the curves a few posts back, it follows the TAD respectably. You really cant go wrong with it.
It is also used in some very respected hi end home audio designs.
 
I am afraid of shouting and listening fatigue most of all. What to choose, HF10AK or HF108(R) ?

I using the HF108R but i didn't heard the others. They replaced a pair of Scan-Speak Illuminators in my speakers. The Scans are not bad but sounded cheap and little nervous to me compared to the absolutely non-fatiguing Faitals. And the horn for the compression driver is a great advantage compared to the bare dome tweeter on a baffle.
 
The HF10AK is one of the few 1 "drivers that allows crossover frequencies that even some larger drivers can't handle. At moderate output levels, obviously.
It's a kind of TAD TD-2001/2002 for the poors.

The HF108(R) is more of a pancake type of driver with a shorter conical exit section and wider exit angle (21 vs 31°).


LineSource has provided a nice analysis of both drivers on the first page of this thread.

By the way, LineSource, I'm a big fan of your informative image collages! :up::up::king::worship:

It depends on:
- the mid woofer's response around the target crossover freq.
- the desired coverage angles
- which (may) depend on room characteristics, intended use etc.


Appreciate your feedback, thanks!
Looking for 1800Hz and up. For 300-1800Hz I got JBL 3730 waveguide (4" throat with the CMCD82 8" compression driver in it, size 30"W x 18"H x 10"D, Coverage: 90º horizontal, -30º/+20º vertical).
Below that I will use a bass tower with 4 B&C 15NW76.
On top of mid WG I have 2435HPL in 2384WG, it sound beautiful but it's huge and it drops like a rock in 9Khz.
I tried to add super tweeter but haven't found efficient enough, it also makes crossover complicated.
So now I want to go simple route and use 1" driver on top of the mid 3730wg.

I did try several Celestion models, PRV, and B&C but didn't find any that sound comparable with 2435 but works up to 15-16khz at least.
The picture is just example of the mid and high WG.
I don't need 40Khz)))

grec, the 2435HPL is designed to play 'pistonic' up to about 15k, but with some additional tweaks (compensation filters) it should touch 20k.
While the 2435HPL and 435Be may not be the very best JBL drivers ever, these are still decent, not in the least due to the precious Beryllium diaphragms.

Are you 'active'? If so, I wouldn't be afraid to boost the last 1/2 oct.

The horn doesn't help here, because it's a CD waveguide (a pretty good one) that requires EQ.
Many people like the performance with the bigger 2451/2450SL behind it.
