I can chip in about the Jordan array, having heard it several times.
1. Ted runs them full range but with some protection from them being in a sealed enclosure. They do go very loud but I've never put an SPL meter on them. In his system they are wall mounted, which will add to the SPL, I guess (no baffle step).
2. He runs them with a powered sub which does run out of steam before the array.
3. They sound great on vertical-axis but if you sit close (within 3-4 metres) and then stand up, you lose the extreme HF.
They do work but then he designed them to be used that way. No idea if other drivers would work in similar circumstances. I've heard similar drivers (Bandor) used in a 2 metre high array and driven full-range. They had a certain palpability to the sound which is difficult to describe but the imaging was weird. But that was at a show and in a crappy hotel room, so difficult to judge.
Aan interesting way to use Jordans or similar might be to take a leaf from the Quad electrostatic. Run the middle unit to HF then filter off the HF in pairs either side, so instead of four, use five with only the centre one running full range into the HF. (Does that make sense?) A good use of Gainclones to balance up the SPLs and make it a semi-active system.
