They're actually a passive design but were activated for the purpose of a proper comparison to the KH120 by adding a Hypex module (in front of the crossover, as I understand it).
Good point, although I have built (easy) speakers before, so that would not be totally offputting.
To me, one important difference is also the size: The DXT MON being quite a bit taller, it might be too dominant visually sitting on my desk.
And with the active design, I can always separate the Neumanns from my other system if I want to, which is a plus, too.
hm...
