Allegro is an interesting compact design that appeared in the German Magazine Klang & Ton.
It uses the Ciare HX160 fullrange driver as a widerange unit coupled with a tweeter.
Link (in German):

91db sensitivity is pretty ok for a 380 x 250 x 280 mm speaker

You could clone the Decware DM944/945. 94dB 1w/1m, 4 ohm impedance and has pretty decent bass response. I owned the 944 for about two years and quite liked it on most music using a SS integrated amp.

5-9 litre reflex would be good. My boxes for these are under development or in beta.

I think I'll order a pair of FF165WK. How far are your beta plans?
(And if not (?), which of the small Fonken plans would you recommend for them?)

Just a thought - I built a pair of bokkshelf/near field speakers from a design by your countryman, Henkjan. These used the Alpair 5 drivers in a transmission line. For 2" cones, these go load and low, and can easily be augmented with a small sub, if required.

... for a box 5-7 litre you need FF125wk. I haven't figured out how small a box needed for FF165 ... likely on the order of 2x the volume

FF125 plans need just a tiny bit of work and they can be purchased. Betas turned out well, but pointed out some necessary fixes in the docs.

The large 165 box is at the beta stage

I find it curious that no one has mentioned the Tang band full range drivers. The 4" bamboo one is plenty efficient enough to be driven by 12 watts in a small to medium room and they are inexpensive. I believe that a 1.25 (liter/cubic foot?) transmission line cabinet would work but I may be remembering the wrong driver specs. Here is something to look at:

Ahh, OK. And for the FF125wk, I use the FE127e mFonken 1v1 (milliFonken – 4.5 litre vented) or the FR125S miniOnken 1v0.1 plans, right?
