Crossing a 10" to a 2" driver is not something that would be normally done for a 3 way speaker with high technical performance as an objective (many audiophile speakers don't have this as a significant objective). You can see from the published frequency response of the 10" it is starting to flap a bit above about 400 Hz. Even a beefy 2" driver like the volt is going to struggle with distortion at higher SPLs crossing around this frequency (never mind radiation pattern considerations). A beefy 3" in a waveguide would be preferable but even then 500-600 may be a better option for the mid. A 4-5" cone is often a better choice for the mid in a 3 way but this may not fit with other objectives for the speaker such as the tweeter.
Well, going by the audioXpress test, the VM527 really does need to cross around 700 - 800 Hz.at the lowest. Volt say that the RV2501 can be used up to 800 Hz, but looking at the frequency response curve on the datasheet, I think it could be tricky crossing it that high. The BM2500.4 might be an easier driver to use if you want to cross high?
The Bliesma is a 3" dome and can cross lower.
Regarding the Volt's waveguide, I'm not sure it has much effect towards the lower end of its range. I suspect the waveguide is there to protect the dome more than control the off-axis.

Thanks for your opinions.
Kerr Acoustic uses the larger vm752 midrange for their K200, I guess it's the best match.

I wonder if it can be crossed lower with steep DSP FIR crossover. 700Hz seems too high. Can 500Hz be possible with 100+dB/oct crossover slope?
