I've got a couple of Barefaced cabs, the Four10 will outman any 'normal' 8x10 I've played through, so I'd expect the same from the Two10 versus the vast majority of manufacturers 4x10.
As mentioned, you may not notice a huge difference at normal volume, or even some people's 'loud', but if you need proper loud and low you won't be let down by Barefaced.
