The press statement sounds promising:
Flavio Naggi, sales and marketing manager of FaitalPRO, explains: "The new HF1440 is a
completely new compression driver, very powerful and outstanding, which joins a series of really
compact high frequency drivers.
Mounting a 3.4" voice coil, we are now facing a market area that has been completely unexplored
so far for FaitalPRO. It is the model with the largest voice coil in our catalog.
Furthermore, it covers a fairly wide frequency range from 0.7 to 20 kHz allowing it to be used as a
high-power driver in any traditional application, including two-way acoustic systems.
Its very linear frequency response gives a neutral and natural sound tonality capable of obtaining a
very high sound quality".
The neodymium magnet circuit uses an 86mm, 3.4" coil, which classifies it as a large driver,
nonetheless the external dimensions make it surprisingly compact.
The diaphragm carries over some technological choices common to other consolidated FaitalPRO
drivers and is a polymeric type, precisely a ketone polymer.
Developed to ensure an unparalleled response to transients, it is able to withstand high continuous
power, up to 120W AES, corresponding to 240W of maximum power.
Designed to operate at a minimum crossover frequency of 700 Hz, it reaches low frequencies so as
to facilitate perfect matching with a woofer.
This makes it excellent even in a two-way configuration as well as a three-way with a midrange.
It was designed with great attention to detail using FEM simulation so as to withstand the important
mechanical excursions related to low frequencies.
The magnet assembly is made of higher quality neodymium with an innovative geometry that
makes it particularly powerful and guarantees a high induction or flux density in the air gap at 2.2
Tesla.
The driver has a 1.4" throat with an efficiency of 109 dB and 120W of continuous power AES and
maximum of 240W.
This product may be used with the FaitalPRO horn LTH142 or the FaitalPRO WG141 waveguide.
Flavio Naggi concludes: "The peculiarity of this new HF1440 compression driver is to allow the user
to set the crossover at a relatively low frequency and at the same time, easily extend the frequency
response up to 20kHz.
We recommend it for use in line array systems, especially in the new generations of lighter and
more compact enclosures.
It is ideal in high power acoustic systems as well as in classic two-way PA systems".

Cant wait to get myself a pair
Really nice driver, indeed!
But you have to keep in mind that the driver efficiency above 10KHz is only 100dB; while the HF146 is much better above 10KHz:

Yeh but I love the way it does not drop off a cliff at 20Khz though
I had long been eyeing the HF146 as a suitable 1.4" candidate for my XT1464 guides, but seeing this is making me wonder if I should hold off a little longer and see what becomes of this.
With the 146 dropping off sharper than the 1440, would this allow the 1440 to be EQd flat to 20khz easier than the 146? Would probably lose a fair bit of the efficiency the 1440 has over the 146, yeah?
Edit: I guess is only a few DB anyways. Would it become less efficient then than a 146?

1)Assuming the two drivers are measured on the same horn, the 1440 would require 10dB more EQ boost at 10kHz than the 146 to be flat, 10 times the power.
2) The 146 is more sensitive (higher efficiency) than the 1440, the 1440 slightly smoother and more extended top end above 20kHz.
3) Become? The 146 requires far less power on the bottom and top of it's range (other than above 20kHz) for the same output, again assuming he two drivers are measured on the same horn- a detail that has not been verified thus far.
