Are there passive subwoofers that will provide me with the same performances or better? I also fear of running out of power from the monoblocs (2x40W).
Which problem will I be facing trying to connect active sub(s) to my monoblocks? Impedance?
Before looking at the KH750DSP I had other subs in mind that I thought I would be able to connect through their high-level connectors.
Here for the Elac 3070 the manual show (page 6) how to connect this active sub to an A/V receiver amp through speaker level-in :

Edit : Regarding my integration of the KH750 active sub, maybe I could send the analog signal from the RME ADI2 DAC FS through balanced XLRs to the balanced XLRs of the subwoofer. Then setting both a low-pass filter for the subwoofer and a high-pass filter for the sattelites (monoblocks) though XLRs output from the subwoofer. Then a XLR to RCA cable will feed the monoblocks amps.
Will this work?
