The RCF has a 3-slot phase plug, the Lavoce a 1-slot phase plug.
These two are very different in the details, it will be interesting to compare them subjectively.

DF10.171K, A520G2, now with the 25-STD-2 (levels won't match):
The exit angle of the driver is somewhere between the STD-1 (12 deg) and STD-2 (31 deg).
It's probably worth making an exact adapter.
(The RCF NDX595 is also very very good, no doubts.)

This is how waveguides are done in 2024 🙂

The effect of the extended throat with NDX595 (the off-axis angles won't match precisely):
Hi @mabat, I have a question. If I upscale Gen2 WG and adapter for a 1-inch driver up to x1.4, what kind of HF directivity can I expect? Will it be about ~1.4'' driver or ~2''+ driver? I'm considering doing something like this with a MEH to achieve ~100Hz with WG directivity. I'll be fine with a rough answer without any modeling.
Maybe it's time for me to start learning how to use ATH soft...

DF10.171K + ATH280EXmk2
(on axis and some arbitrary off-axis angles)
It seems that the (built-in) extensions in these smaller WGs may have too abrupt terminations (due to their wider coverage angles), I don't know. Of course with a DSP this is no issue, but still...

I must correct this. It seems like a single slot from the exit side just by a brief look but it's actually a 2-slot design.
The DF10.171K:
Anyway, obviously the exit wavefront is really well behaved. They claim a FEM optimization and I believe them.
The back chamber is without any damping and it should be easily possible to make a custom rear cover for this driver.
BTW, there's a similiar driver, DF10.171M, with a different diaphragm. I leave that for others to try.
Overall, I think this is a pretty good substitute for the (no longer available) Peerless drivers.

One wonder if after reassembled it becomes really air tight... back ver against metal, the terminals coming out of the back... does this matter?

There's nothing unique about the assembly that would be difficult to reproduce, you just put it back. The drivers are designed this way, so you can easily replace a damaged diaphragm. It's also an opportunity to check everything is fine.
There was a discussion a few pages ago about coaxials integrated into the waveguide. Peerless announced a new oval coax (10″ wide) with moldable custom dispersion patterns. No further information or measurements yet, but there's some freshness to the idea.
Wouldn't the Lavoce DF10.172M be an interesting option given its probably easy to equalize frequency response?
Regarding a final absolute SPL curve, a lot depends also on a waveguide, so the picture above only tells you that the driver per se is probably smooth enough to work with easily, but not much about a required EQ in a particular horn. But I'm not convinced that a stronger magnet is necessarily an advantage here. It can add a few dB of midband sensitivity (which is already pretty high anyway) but not always improves things regarding EQ.
If you look at the DF10.171K with the A520G2, there's already very little that needs to be done. But of course if anyone tries the other variants of the Lavoce drivers, it would be more than welcome.
