Feedback on 18Sound 10NDA610 as midrange

FWIW, I'm using Hypex UcD400Rx for midbass. Subwoofers are powered. 400W per channel is way overkill for midbass, in my opinion. My midbass is now going from 80 to 350Hz in my current speakers with 2x6" per side, although probably going to go somewhere 60 to 400Hz when I move to 2x10" per side in sealed box.

I've been very happy with the UcD modules. If anything, I would like something that consumes less power when idle so I would keep them on all the time. They take about 15W each and in this day and age I would rather not have 30W on all week to use mostly on weekends. Note is a very minor issue: I turn them on on Fri AM and turn off on Sun night...easy 🙂

Sorry for the slight derail. I was looking at the Digmoda units. They seem to be very highly regarded,
I want to power 2 x Beyma 12LX60V2 in a 120 litre cab for the bottom of a 3 way up to around 400hz and crossover to a 2" BMS Horn Mid and Faital 10AK Tweeter.
 
Have you seen dispersion curves you can point me to?
Thin line is measured at 45 degrees off axis. Ideal for AMT (TPL) or horn loaded high frequency driver.

Was looking at this driver again. The measurements I posted a couple years ago were actually in the mid to high 120's at 1m. Recently discovered that STEPS was putting out more signal than the other programs I use. No wonder it was loud.
