Nice driver. The last price of the FR speaker/pair, named MADOTEC - "Enceinte Bleue", was about 8,900.00 EUR = 12,232.82 USD.

Price for a pair of raw drivers should be around 2.000 EUR. Thought of using them in an aperiodic enclosure, but curious what they sound like.

It will be an interesting experience (... and expensive.)
I can give you a link for a forum/thread where you can post a message asking for "likes" and/or linking to your thread.
Just leave a message there, for them to visit and leave their opinion here:
Project Ryu - DIY Field Coil Loudspeaker

Plus, I have the musical audition of this speakers in a magazine.
The name is "Stereo Prestige & Image nº 84 Decembre 2013" - "Madotec Enceinte Bleue" you can read it here.

Synthèse de l’esthétique sonore selon Patrick Vercher et Benjamin Boucaut :

« Une restitution des plus musicales dans toute l’acceptation du terme (…) avec un sentiment de plénitude sonore qui atteint des sommets »
À bientôt.

Default EMS LB12EX

I'm running LB12EX in ~43L enclosure, no crossover on LB12 + Fostex t500a mkii high-pass 12dB @10kHz + REL T5 @60Hz
I’m not yet ready to go to too much details, speakers are working for just a few week, but first impression is very good, refine and very dynamic. Very sensitive to a field coil power supply quality.

I wonder if a gel pack battery power supply would work well.
Wheelchair batteries are fairly compact and robust, these days.

Should be OK, but you will have no ability to adjust exc. current.
With the ability to change field coil current from let's say 0.8A to 1.5A you basically have infinite number of differently sounding speakers in your room.
BTW, voice coil is 16ohm, field coil is 8ohm.
