It seemed I posted in the wrong thread previously, so no response there🙁 http://www.diyaudio.com/forums/showthread.php?postid=1845661#post1845661
In a wide range application with big throat front loaded horn, the effective load provided by the horn can not extend very high. So normally a (wide range) driver with rising response would be a better match.
However I had an amazing experience on Oris 150 with 6" Jordan (the model in pottery vase). The Jordan is far from the uptilted kind of speakers, or just the opposite. I just 'put' them together loosely without any physical fixing. To my suprise, they sounded great. The moderately colored 6" Jordans played very dynamically with the front horns. Lots of effortless, deep cut, almost magnified details were projected by these little drivers. And there's no ill-effect in tonal balance or worsen midrange colorations in my impression.
Quite a lot of good reviews on FF225K around here. I myself like such drivers intuitively, too (wide-ranger without whizzer). Such a low Q driver should work well with horns. However I have not seen any FF225K mated with front loaded horns.
With its own inherently (and relatively) smooth response, when mated with a FLH (e.g. Oris 150), would it become too 'dark'? How would it compare to some other uptilted drivers? Like FE206 or Lowther? Had a short period of experience on PM4 + Oris 150, I liked the sound very much. However, the expense differece between Fostex and Lowther is almost ridiculous. I'm wondering how people justify it.
Any inputs?

I was always under the impression that the FF225K was one of the less popular of the bunch. Probably something to do with the xmax figure scaring people away. On the other hand, everything else about it seems nice, and I've had my eye on it for a while now. I do wish there was more info out there for it.
I believe the main advantege and interest in the ORIS horns is to counter the effects of rising response in very high (Low Q) efficiency drivers. If you choose a driver with a natural rising response, the ORIS horn will help bringing down this response to flatten-out the overall response.
The FF225K has limited response and would probably not make full use of this caracteristic. Maybe the FE206E would be a better candidate, as would be the FE168Z.
My 2c.

Thanks for the responses 🙂
I'm also considering FE206E, but still worry about the whizzer though. It seems there'd be some inevitable irregulations in 2-4kHz range with this kind of drivers and a mess in higher SPL🙁 In the experience with Lowther (PM4) in Oris, I found the "collapse" happen in quite high of SPL. I would accept this limitation now. Just not sure how much FE206E can do (as compared with Lowther).
I think of the Supravox, should be excellent, but is as expensive as Lowthers and I've never seen or heard it in person.
I also think of some of the pro sound 8" midranges. However I don't need those relatively heavy cones (for their high SPL applications), although they have very strong motors and low enough Q. And they can not play high enough thus a 'troublesome' xover point to mate with tweeter.
I think the sound qualities are different between [stronger motor+heavier cone] and [weaker motor+lighter cone]. I tend to choose the latter now, should be better in the 'downward dynamic range', I guess.
Any other light cone/whizzerless wide-rangers in your mind? Thanks a lot for sharing and I'll also keep searching, too.

You might find a need for a tweeter with the FF225, but otherwise i've only heard good things.
