Hell yeah!
Just remember that in some cases a subwoofer causes more problems than it fixes in monitor system.
Checklist before investing in a sub like this:
1. True reference monitors and not stereos with bass bost or artificial color added.
2. Large enough room, smaller rooms or cube rooms don;t work well with subs.
3. At least some acoustic treatment like bass traps, broadband absorbers, or first reflection treatment.
