Louver based, PVC insulated Segmented Wire Stator ESL

Look on page 11 of the downloadable manual and you will see exactly what I am recommending being used in the fancy Sombetzki ESLs.

This reference was posted by Calvin on the Sombetzki thread, in this forum recently:

The stator substrate looks like a louver.
These monitors have quite interesting spec. Unless I'm missing something they are very sensitive (100db) for FR ESL with rather large D/S= 4 mm.

From the manual:

Application directed speakers for listening distances of 60 cm ... 100 cm
Maximum SPL in the range of 100Hz ... 8kHz 100 dB / 1m
Frequency range 37 ... 21 kHz ± 3 dB / 60 cm
Impedance 4-8 Ω
Diaphragm stroke ± 4 mm
maximum permissible Amplifier power 50 W
230VAC 50/60 Hz
Power Consumption Less 0.3W
Power supply Small Appliance Inlet C8
Loudspeakers 1 piece electrostatic broadband transducer
Dimensions : ~ 60 * 40 * 2 cm
Dimensions H x W x D in cm 66 * 35 * 51

... the time tested Acoustat construction technique of insulated wires glued to louvers.

Procuring good "infra-structure" can jet-propel new panel construction because many DIY builders are stuck at Step One figuring how to make a large flat cell. So finding any kind of suitable rectangular or round plastic piece gets you going. If your lucky find has lucky spacing, might be worth seeing if spray-painting with conductive paint will work (like DW). Otherwise, the time tested insulated wires are a good idea.

I don't know when Acoustat tried it, but Janzen and Denneson were winding garden-variety light "hook up" wire in the '60s using small square and round plastic forms. (BTW, you can sand the plastic piece on a flat surface to ensure it is flat.)
