Estimated F3 65 Hz or so, F10 50 Hz, where you will need to place them lower.

So treating them you would make them a 94dbel sensitive drivers?
No. With treatment they loose 1/3 to 1/2 dB do on the order of 88-89 dB (5 dB more than the A7.3)

First FF125wKeN are ready to ship in a range of colour schemes/

dFonken125 planset is available, still needs some fleshing out (which will happen as people ask for specific material sizes). It is part of a driver purchase or available separately -- email me.

One more question.
Considering the quality of sound (purity, scene, bass reproduction), would it be better to use a fonken design or a bass reflex?

A Fonken is a bass reflex variation... but without some of the problems associated with typical BR.

... but with less gain in the bass IIRC - it tends toward aperiodic because of the high aspect ratios of the slots.

I suppose the increased flow resistance would mean that the driver isn't completely unloaded below Fb, though, which is useful on the power handling front.

Given that the trapezoidal fonken is really beatifoul, would it be better to use this kind of enclosure or a bass reflex with 18-20l? I mean considering it from a full range sound point of view (not only bass response, but medium and high too).

The increased flow resistance, ie R added to vent, also makes the box less sensitive to dynamic changes in the T/S parameters.
