@mijostyn , I am using the XLR inputs for home theater. There is a toggle switch for RCA on the back and I have tried some two channel preamps so I can switch between HT and 2 CH preamps if I want. I can’t give it a digital cable.
The Active 20 measurements are HERE
As for the crossover info see the specs here:

From the Active 40 review :
Audiophiles just don’t readily accept the idea of their speakers being self-powered. But active loudspeakers have some distinct advantages over their passive counterparts. In fact, when I asked the designers at Paradigm which technology was better, active or passive (since the company makes both types of speakers), I couldn’t even finish my sentence before the word "active" was rushed back at me. There was just no second thought about it.
