These have a more limited horizontal dispersion than the BMRs, but Erin found them to have a wider soundstage (correct me if I'm wrong, Erin). If that's the case, I wonder if we have to consider whether reflections off the front wall (the one behind the speakers) contribute to a narrowing of the soundstage. Certainly ipsilateral reflections widen the soundstage, and the BMR should have stronger ones. If reflections off the front wall are perceived as a negative (though I suspect they can add a sense of depth... but it may always be the same depth, rather than recorded depth), I think we may also ask ourselves whether we want complicated cardioid speakers, or if we just want well designed on-wall speakers.
