O.K., first try with 275nd diaphragms on 2426H motors, here with 2342 horns, LE14A woofers.
It does not appear that these will work as drop-in replacements in most systems without crossover modifications. I tried various horn/crossover combinations to get this with AM6212 HF and NL200t3 LF for a listen without EQ. They still need help around 5 kHz.
Compare impedance curve on 2342 to Giskard's run with standard 2425H on 2344A here:

I'm not seeing anything anomalous.
Mellow and smooth, aquaplas coating on this thinner titanium diaphragm mitigates the characteristic harshness, even with full HF extension.
Also tried them on 2344A with 4430's N3134 crossover (bottom). Can't dial them flat. I don't think it's an alignment issue, since both drivers behave similarly.
More once we complete the 1" driver/diaphragm study here....
