Around 800hz-1khz is enough.
1" vc mini-bms had no problem crossed at 1,5k in a shallow waveguide of Mummy
Compared to that the Yuichi loads the driver stupidly good.

Look forward to your comments. I didn't like the polymer dome as much as a nice metal diaphragm. This was in the HF146R which is too big to do well up high imo.
It looks like it works great for rings and smaller domes.

I use the HF146 (without R) and it does very well IMO-- also at its upper end. But I must also say that my hearing starts to drop between 12 and 14 kHz. The diaphragm of these drivers isn't that large at all. It is around 2.5" which is a good compromise for a driver that can be crossed quite low at domestic listening levels and used in a two-way system.

Hi Legis,
I've been following this thread from the start and I must say this project is a beast!
I would like to get your opinion on mating the HF1440 with this 18sound 15NTLW3500 in a 2-way, will be using Hypex Fusion. also, what horn would you recommend?

That is a combo that I was eyeballing as well and which I think could be very cool. But I was also wondering which horn to prefer.

I would go LTH142 or XT1464, yes, response is mystery, but atleast they are cheap non metallic horns.
Correct, but one TAD alone would set you back almost as much as four of these. OK it is apples to oranges but the 18s drivers that I had in my hands so far did all have a very high build-quality.

As do the Faital's. Fair enough, though I'd like to be able to do a sound quality comparison.
Stupid thing I did once was to misconnect a DSP .. switched the HI/LO on a 2-way on one channel. Faital 15" and a AMT. Wasn't till I was listening to a particular track that I caught it .. after an hour or so. That's how smooth the 15" is at half the price. What does the extra $250.00 get a guy?

It is difficult to say without having one to compare. I guess you used a 15pr400, right ?One advantage of the new 18s is its dual-gap motor. It was developed with the intention of being used over a large bandwidth. It has very low inductance, symmetric drive and also a demodulation ring.

phase_accurate ... yes, the 15PR400. I got a pair, new, for $400 a few years ago. I'm happy with them. They're in a 185l sealed box. I did model the 18Sound a couple days ago and it'll work in a med size BR enclosure, nice low frequency extension, looks like.
ErnieM .. for home HIFI I wonder just at what SPL this will be a factor. I'll sometimes listen at 100db (3 meters) and that's plenty for the wife downstairs 🙂 I've tested the Faital at this level and THD isn't an issue. I can see the advantage in a PRO audio setting but I doubt they'd ever get to "shine" around here. I'd love to be able to hear them in a 2-way app. though.

Charles,
nice to know I am not the only one thinking of a 2-way implementation.

I've thought of the XT1464,it's getting positive feedback from diyers.
Thanks.
Ernie,
My mind was almost made up on the Faital 15PR400 then I saw you posted a link of the 15NTLW3500 in one of the threads...you're a bad man Ernie and also you, Legis 😀

More bass without sacrificing midrange clarity is the advantage.
Hi puppet,
How low does the 15PR400 go in the 185L sealed box?
Thanks.

I am already using an XT1464 together with a Faital HF 146. Sound is nice and, apart from achievable level and dynamics, very non horn-like.
It is just the urge to try something new once in a while. The HF 1440 and the 15NTLW3550 are such beasts that draw one's attention to themselves.

When simulating the 12" Faital 12pr320, the f3 is very near the 15" big brorher...but some say the 12" is snapier and a better marriage with a horn aound the often seen 800 hz cut off?
Has someone tried both with a 1.5" horn like the 18thSound ?

a3cervo ... when cab is about a meter away from boundaries, F10 is around 32hz. This is with a LOShelf boost of 5db@84hz. No other EQ. Farther out, (2) meters or so, F10 is around 40hz. Same LOShelf boost.

It really just comes down to spl requirements. The Faital is a good driver if you only need a couple millimeters of excursion for your enjoyment.
