The wider-baffle speakers that I’ve become acquainted with and auditioned - I’m thinking the larger Harbeth models, Devore and to some degree Audio Note - all have impressed me by "disappearing" and soundstaging much more than I would have expected given their looks, and given the usual audiophile ideas that narrow profile speakers image well/wide speakers don’t.
That said....
It’s also the case that while those speakers did surprising imaging/soundstaging/disappearing, they also weren’t near head of the class for those qualities. In each case I have found soundstage depth somewhat flattened, and a sense I can hear the speaker contributing to the sound (which as a hunch could be due to the thinner-cabinet-working-with-resonances approach also taken by those speakers). Many narrow baffle speakers seem to disappear much "more" and with greater depth to the imaging.
