I know someone must have mentioned this already, but what about using a very large array of tiny speakers, so that it would work well for an OTL tube amp driving them in series?
Note: I've crossposted this in the Loudspeaker forum as I couldn't decide which was better, so please reply there:

Hi,
Someone actually beat you to that one already but the answer remains the same:
If you want to adapt your speakers to the amp of your liking then I've nothing against it.
Just keep in mind that OTL amps put out their best at highish impedances but there are limits to it.
Assuming the array of say, 8 Ohm speakers, consists of a purely resistive load then that theory may fly....
In reality however, any resonance peak, hence an impedance peak will be exaggerated by the array.
This will look like an impossible task to most amplifiers an OTL included.
The solution to the problem is relatively simple but you'll have to correct for any exorbitant Z peaks in the speakers to make it look as a reasonably even handed load to the amplifier.
This can be done at the amplifier end but IME it works best at the speaker end of the business as the LCR of the cable run can be left out of the equation that way.
In which case the OTL would offer a very good choice indeed.
I am however by no means a speaker specialist, just telling you what someone with hands on experience has told me....
Cheers,😉
