Thanks Dave. I had to rewrite my post was in the middle of something. If I buy the FF85wk do I need a still need a tweeter? Mr. Daniel
This is an interesting driver. I noticed it is slightly hot rodded compared to the stock FE103EN. The anniversary version has a shorting ring and very flat impedance, and a slightly larger magnet (226g vs 193g). I'd guess the resolution is a little better.
Also, with that flat Z curve, it would be the perfect choice for a wideband midrange in a 3 way using true first order crossovers.

Did I understand correctly that it has a surround that has less compression?
I have not heard it but it attracts me more than the FF105WK. May have to model it to see if it will fit in the FF105WK metronome.
Madisound appear to have some: The Madisound Speaker Store
Not sure whether the damper reference in the text is another way of saying 'we've changed the spider' or if they've added something extra. The copper plated pole-piece & inner magnet is welcome. Looks to me from the measures like it has the same resonance issue at ~2.2KHz that the standard 103En has; since the text suggests they've changed the paper mix, that's presumably either suspension or geometry related -the frequency suggests the latter; possibly a standing wave across the cone. Probably optimal about 10 - 15 degrees off axis to flatten out the lower - mid HF range. Nice enough little unit, & should appeal to those who love the 103 sound (a legion of them, esp. in Japan), or those who want a quasi-collector piece, given that it's a little bit of history.

Oh, to have the budget and nothing better to do, but design/build 'proof of concept' speakers! If the specs, response are reasonably accurate, then the 16 ohm version in particular appears to be designed specifically for a SET driven ~40 Hz compound horn and the 8 ohm for a ~matching impedance version.

If you are looking for a 16ohm 4 in driver with 91dB sensitivity, smoother response, and 30watts power handling, check this out. Also half the price.

They're about the same size, but they're not designed for the same thing.See post#11 and yes you could use 4x 16 ohm per speaker and achieve 4 ohms (parallel then parallel) with about twice the sensitivtiy vs. using a single.
