Whatever choice you make to benchmark the KH150, you have to understand a monitor is made to listen to in the nearfield. While hifi is more for living room with midfield distance >2.5 meters. So serious dev include this important side of the listening room layout.
one guy among the serious ones that include this side is Göran : https://www.audioexcite.com/ his 2 ways are made to listen to for a certain distance 2.5/3 m circa.

I don't want to dismiss your plan now, but a big part of the sound of the KH150 is that they use a paper woofer with almost no resonance and a soft dome tweeter that also has no resonances up high. That makes it sound so clean and relaxed. Ther are no resonances that need to be tamed. You tend to do do it reverste, a metal cone woofr and a harddome tweeter. I'm sure that that also will give a very clean sound when done right, but it won't have the clean non-fatiguing at all and non intrusive clean sound that is typical for Neumann/K&H speakers since decades. It will be more on the Genelec side of superclean monitors.
But for the rest, an interesting tread, i'm subscribed 😉.

It's a hard dome tweeter and the older, low resonance paper woofer in the KH120 was MAYBE the cause of one of the things I didn't like about this speaker. (Midrange was not 100% accurate in comparison to better speakers). KH150 and KH120ii seem to have more detailed midrange - probably harder/less dampened material?
I never had a soft dome tweeter which sounded "clean" compared to a Beryllium - they all bring a little sound to the stage ...

... and some are saying aluminium or magnesium is better than Be for brass and percussions ! I do not know who to believe today !
I would not buy a tweeter especially for 2 instrument groups ... 😀
Percussion and brass can be heard more "intense" with AL (I directly compared Bliesma BL and A). But that does not mean it's more "natural"! With the A version I hear "more" cambals with drumset, but with the B version I can hear the quality of the cymbals.
I'm a drummer and like to have a lot cymbals 😉 ... but Beryllium is better for detailed, natural and still relaxed listening. Aluminium would be for "fun" hearing for me. And silk for "relaxed with a glass of wine" hearing.

KH120 and KH150 are labled as nearfield cause they can't produce the level you need in 3m distance in an professional environment with low enough THD. This doesn't mean they are not working perfectly in 3m distance, better as most speakers you can buy!
You should not get closer as minimum distance the manufacturer tells (cause of driver distance to each other) but when SPL level is fine for you there is no max distance where the speaker is not working enymore.
Genelec has great information to this topic: https://www.genelec.com/correct-monitors
Interesting is also the distance for "direct" sound in these very controlled rooms with 0,25s reverb time - about 2m. In a normal living room, estimated 60m³ and 0,5s reverb time you get reverb radius 0,6m for an omni source! Get some directional speakers and extend to maybe 1m.

This is an often missunderstood topic - if you have questions left it's probably worth a new thread.
