Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: ELAC Debut ConneX Adsum measures better, ELAC Debut DCB41 costs about 20% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 66Hz anyway, which makes the cheaper ELAC Debut DCB41 much easier to justify. In a large or open-plan room, ELAC Debut ConneX Adsum has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, ELAC Debut DCB41 is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
