It comes down to
1. Titanium vs Polymer diaphragms, in theory. The 204 seems to have a little more going on in the top octave but I can't say if this is breakup related or not
2. I've been told the 204 is really a 1.4" compression driver (HF140) with a 2" adapter whereas the 204 is a real 2" compression driver.
I'm considering using one of these compression drivers to a klipsch belle mid bass
1. desired (active) crossover ooint around 400 - 500 Hz to
2. two way configuration using either :
a. one of these drivers on an M2380 Constant directivity horn (using CD equalization)
b. the 1.4" version of the HF200 driver ie. the HF140 with a tractrix horn (LTH142)
Faital Pro HF200 - Faital Pro HF200 2" neodymium high frequency compression driver. Faital Pro HF200 HF drivers available here at US Speaker.
Faital Pro HF204 - Faital Pro HF204 2" neodymium high frequency compression driver with a ketone polymer diaphragm. Faital Pro HF204 HF drivers available here at US Speaker.
Of course none of these specs tell me how the drivers sound - apples to apples. Has anyone compared them ? I'm open to other suggestions
Thanks

Have you read the application note?
Both drivers need to be cut off at 900Hz with 12dB/oct.
The frequency response above 10kHz is better with the HF200.

Yes I have. I've also come across several anectodal references on the web indicating that these drivers will work much lower in a HOME environment. For example

Spec sheets don't tell the whole story, although they do offer a lot of teasers 🙂

Someone around here got good results from the hf144 on a 18 Sound flare. They liked it better than faital's tractrix and pyle's horn. I believe they tried crossing as low as 500hz with no problems in a home environment.
Al from usspeaker recommended the hf146 or radian 745neo last time I asked for high power >1 kHz use.

if you have access to them, the 18sound compression driver 2060 and 1460 are a lot better sounding that these. the 1480n with coated titanium driver is the best of the lot but its very expensive..
More details please....been interested in those for a few years. Also read people prefer the BMS coaxials to the 18 Sound line up. So many options.
"Both drivers need to be cut off at 900Hz with 12dB/oct."
For high power PA.
"Someone around here got good results from the hf144 on a 18 Sound flare. "
Sounds better for sure, but doesn't go as low.
"Also read people prefer the BMS coaxials "
Have three pair, not sure they are the best for home use.

Djk, what driver / horn do you recommend, for my purposes? Eq and Crossover would be active via a minidsp
FP has 2.56" and 2.91" diaphragms that they use on both 2" and 1.4" throat drivers. All of them are rated for either 40 or 50 watts with a 650hz crossover. 2" throat costs more, and usually that carries over to the horn as well.
I've done a fair amount of testing on the HF146 with a 2.56" ketone diaphragm. It is breaking up above 9 khz, but much like a very well dampened paper or poly cone woofer the breakup is very well controlled with approximately +/- 2 db wiggles to the top of the response that extend out to 17 khz. A larger titanium diaphragm is going to look much worse.

Thanks for your response. It's looking like the HF146 is turning out to be a good overall performer at a decent price. I'm also curious about B&C's top of the line drivers. They're pretty well behaved except for a little breakup at 15.6k.
"Have you a pair of 4594 or 4593 for sale?"
Sorry, no.
" what driver / horn do you recommend, for my purposes? "
I'm really fond of the JBL 2384 horn with the 2435HPL driver (beryllium), it should be crossed at 650hz or so.
"A larger titanium diaphragm is going to look much worse. "
The large FP titanium have a 10dB peak around 15khz, some like the 'detail' it adds.
Sorry, no.

FWIW, The HF144 is a 1.4" compression driver with a ketone diaphragm. FaitalPRO | HF Drivers | HF144 .
If my klipsch belle module can hit 500+ Hz comfortably, this sounds like something that could work. I guess we'll find out soon enough.
@djk, I'm sure the JBL sound great but they're way above what I can spare. Thanks for the input, though, and for steering me away fro the 2380 horn

"That needs to be zoomed in with a lot less smoothing. "
Sorry, graph was from a source I have no control over.
Will this do?
"I went to an 18Sound XT1464 which is by far the best so far"
Of the ones he tried, I would agree. Check the size though, it is a bit taller than what a standard Belle can use.

Carl Huff got his LaScala to 800hz with the Crites woofer.

djk, Thanks for the tips.
1. The kappa15c should worker higher than the stock k33 woofer so I have a reasonable chance of success. I also put in some corner reflectors which shouldn't hurt.
2. My belle is a custom one - off DIY build so I can build it to whatever height I need. In fact, I'm considering implementing a removable (and replaceable baffle on the top section). I'll finalize that design after experimenting with the mid-bass porting mod.
