Throw us some measurements

Where can you get them for that price? The 1400 is already around € 400,- a pop.

While ago it was on TLHP, don't find link that showed the prices now but here it was mentioned https://www.diyaudio.com/forums/multi-way/338806-acoustic-horn-design-easy-ath4-279.html#post6270037

edit: just log in and see the price Compression driver FaitalPRO HF1440, 8 ohm, 1.4 inch

It was around 50 days when I ordered them. They were delivered in less than half of that time - you may be lucky as well

I guess you have the only ones that were ever manufactured …..

That is one of the worst cases of driver-porn so far ! I am going to report you to moderation …..

Fun aside: Could it be that there is also a version with push terminals because faston is explitely mentioned on the package of your's.

What is porn?

- I don't have a clue.

Nice drivers, would be interesting to compare to td4001. How they sound? Do you have measuring equipment?

 

[Audio Elite]

Waiting in anticipation for impressions!!!!
Had my eye on this for a long time

Hah, also ordered a pair from THLP along with an Eminence HA-14-2 adapters from Blue Aran.

Will be trying them in a 2" biradial horn closely related TH-4001 (Usher D2/D3). The reference driver is TD-4001 with original be-diaphragms. Lets see how these very interesting new drivers sound and measure, interesting also to take a peek inside them...

The Usher bi-radial horn has the fins further away from the throat than original TH-4001 design and beams the HF more, which might be good for the Faital's falling response, might compensate for it somewhat at 0deg.

I also read some prefered to the Faital HF10K 1" a 1" from 18THSound for the TD-2001 of the poors !

HF1440 disassembled - basically three parts. The outer diameter of the diaphragm is 100 mm, the inner 72 m (86 mm voice coil).

The press release claims a lot of time was spent refining low frequency behavior. Wonder how it compares to other large format drivers down low. The high frequency is very smooth compared to most.

I was looking at 4" diaphragm compression drivers for a project but then this showed up last week for PL+S. Looks like many are going to ring-radiators for their flagship products.

Although comments on a comparison between the 950PB-Be and Axi2050 makes me pause for a bit. The person claimed that the 950 had noticeably higher resolution despite being matched very closely in frequency response and level.
On another forum someone has a JBL 2452H-SL ranked slightly ahead of the D2 for their preferences.

Maybe it has something to do with a large piston moving very little vs. small section of a ring trying to make the same spl....I don't know.

Guess I need to try both.

You and me both.... Do you have a link for the website you read the comments on? I paid 700/pc for my Axi's I would consider a 950Be if I could find it for similar...to compare and contrast.

Ain´t the guys filled those hollow phaseplugs on BMS drivers?

 

[mabat]

Sorry, I don't follow.

What caught my attention is how they connected the back side of the diaphragm with the internal volume of air under the front cover, apparently to increase the compliance (I can't imagine any other function - these are quite narrow channels).

Interesting! Thanks for sharing.

The area of the ring is about half of a 4" dome. JBL specs 0.5mm xmax for their most recent drivers.

Looks like they aimed to roughly match the output of large format drivers without breakup in the upper octave while avoiding the cost of Beryllium.
