Mismatched dual Sub models but same Brand?

[Annoyed82]

Would it really matter if one sub was a Klipsch R-100SW and the other a Klipsch SPL-100,?They have same very similar freq responses and more than enough watts for my needs, same brand, same sized driver, both ported and front firing. I see a number of similarities on paper between them, the differences seem subtle so probably wouldn't be noticed to the naked ear and only on measuring equipment.

AVR is a Denon X3700H and for sub placement I'd be looking at one in front right corner and the other diagonally opposite in rear left

I'd say they'll work just fine. I've run systems with two different brands and it worked fine.

I'm using 3 different subs at the moment in the same system. So far no issues, but I don't play at levels where the weaker sub might start struggling.
