Excellent. I should see my FF85 & FF125 wed or so then.
I see they have inhereted the dust cap from FE138eSR.

No sign of the 125 yet on the listings, all the others are there though.
Re the dustcap, seems to be aluminium. I think that (in magnesium form) was in fact first seen in the Fostex range on the Japan-only limited edition WG850.
Colour me a bit disappointed though. Granted these are not supposed to be top end models, but I'd still hoped for a little more; they look reasonable units for what they are, but they don't appear to have moved things on at all in engineering terms. Perhaps that's a consequence of trying to use them to replace two ranges (FFxx5K & FExx7E), or perhaps they're struggling a bit following the apparant departure of some of their design / development people.

It appears to have a high hysteresis surround, so a damping ring like required on a rubber one may be a good tweak.

the 225 seems interesting when adding a supertweeter.
However it has a scary bump at 3khz - I expect an irritating bite in the sound there if no corrective action is taken.

I'm really curious to hear how these work out, especially in horn loaded boxes. I can't help but wonder if they are a suitable replacement for the old FF85K. It seems the total Q is a little higher and the BL is a little lower, which isn't what I think I'd want for a horn loaded driver.
Moving mass is spec'd a bit higher and excursion is less, which doesn't seem good either.
the frequency plot of the new FF85K seemed the best one to me. I expect it to be interesting in a small box, actively filtered & biamped with a subwoofer.
Wonder when/if they will present a new all-out assault on the 8" full-range concept? The interest in these drivers is probably bigger than ever, and at least here in Europe the market is ripe and ready.
Imagine an improved version of the FE208ES-R....

wimped out towards BR favored specs - adding a tweeter super or not isn't FR.
An externally hosted image should be here but it was not working when we last tested it.
That's a nice build freddi!! I don't recall that one with a k-tube horn inside the enclosure up before. OTOH I often can't recall what I had for supper yesterday
Where can I learn some more about this build - like details??? 🙄
I have not seen the new hybrid back horn and bass reflex suggested build enclosure shown for the FE126en previously. Is anyone thinking about making it?
that's one of Carl's builds. He also sometimes augments Fostex fullrange with the K-tube waveguide - (above made of layers of maple veneer for inertness)
FE206 work pretty well in K-couplers - here's another one by Carl

Why are they still not circular? It improves the aesthetics so much more. Or does this affect rigidity and performance. If so fair enough.
You mean the frame? It's a fairly standard stamped metal job, so outright performance is not on the agenda. I suspect it's the same frame as the old units. Keeps costs down. As for aesthetics, beauty in the eye of the beholder & all that. I'm not overly bothered one way or the other, although circular would be a bonus (& a whole lot simpler to flush-mount for many people).
Yeah that's what I mean, I wouldn't mind paying a bit extra(a few quid) if it was circular or came with plastic ring that went over the top so it to it sloped nice down at the sides like some drivers have. never known what there called or if you can get retro fit items. At least this way you could have the old style cream drivers on show if you don't have a router to rear mount them.
hey planet10 - when you get time post some initial impression on FF125WK
