Just curious, anyone used the Jordan Eikona as a mid in a 3 way. This lauded as one of the best full rangers and can dig to 40hz in the right box and touted to have “holographic imaging qualities” (puts the BS Dictionary away!).
Looks like it could do 150hz to 5khz in a 5l sealed box supported by a 10” (sub) woofer (e.g. SB29NRX75-6, Scanspeak 23w4557, Dayton RSS265HF-4, L26ROY) And a small ribbon, 0.75” tweeter Or Fostex Supertweeter (e.g. Neo CD1.0, OW1, T90a).
However, not seen any off axis measurements so a bit of an unknown.
Thoughts?

Looking at the FR graph, “holographic imaging qualities” = exaggerated high end because of the peak above 8Khz, & the bump in the mids 250-400 Hz is dubious. It's not particularly efficient, & ridiculously expensive, so I'm sure you could do much better with a dedicated mid driver
Many "fullrange" speakers have a HF peak on axis because they are designed to be listened to off axis and the peak gives a better power response.
