NRC measurements for the 805 D4 are up before the review. The response is definitely... interesting.
And the Listening Window
On the plus side, props to B&W for doing the closest thing to a 'Batman' frequency response I've seen yet, ears and all:
In all seriousness, horizontal directivity looks decent, I think. Hard to tell for sure without tracing the data. B&W tends to have completely different directivity even among speakers in the same family though, so I wouldn't extrapolate this to the other models. *shrugs*
