Subwoofer Pairings

I understand the need to pair a subwoofer with the speakers from the standpoint of tonality and volume. So, “no less than” a certain sub will do for particular speakers.

But is the reverse also true? Would a very high end subwoofer be WORSE than a more standard subwoofer with particular pairings?

For example: I am running my KEF R3 METAs with a REL T9/x right now. REL suggests a pairing of a T7/x on their speaker pairings website. Would a S510 be WORSE than either of those? It seems counter intuitive to me.
