Active DIY project - recommendation needed

Can anyone of you guys provide some information regarding the following speakers:

Acoustic Design Online - Doppel 7 aktiv

or

FUSION-3

Hope, that I'm in the right section here. I thought of building DIY Amp and passive speakerset for stereo, after thinking about my habits and my current passive (living-room) and active (bed-room) setup I must admit that I'm more the active character... 😉

So I want to work with Roon - Allo's Digione Signature Player - Preamp - Speakers. My living room is about 5 x 6 meters.

Any other speaker kit recommendation is more than welcome, I contacted Udo and Troels from the above mentioned speakers, they are both very very helpful. But I want to get sure before ordering. Any advice?

Cheers!
