Yes this has more opportunity to adjust the sub it even has YPOA room correction
But it will strain your budget to also change amp ? Have you already bought the n600 amp and you Dynaudio speakers ?
I’m not an expert on this so can’t really suggest subwoofer brands .
Our member
@sweetchaos has a list .
I've created a *slightly large* subwoofer comparison spreadsheet. :D Info: -==Link to my Subwoofer Comparison spreadsheet ==- https://bit.ly/SubwooferComparison

Prices vary locally here in Sweden the difference between the mission sub and the kef kube is not much for example.
SVS subs would be very budget friendly for someone in North America .
Have you considered the used market.
The list you compiled is that what you can get at a good price near you.
My experience is that dedicated subwoofer manufacturers products cost less for thier performance than a normal speaker brands subwoofer products
Here is one sub rsl speedwoofer considered good value in the US
