Regarding Maggies, consider the .7s instead. They’re better balanced, more efficient, and more dynamic than the 1.7. Despite being 2-ways, the .7s give up nothing in midrange quality compared to the 3-way 1.7s. The only real advantage of the latter is possibly a higher max SPL (at the cost of more juice).
Maggies tend to sound best with an isosceles triangle setup, the panels placed on the short side. That might be an advantage in your 12’ wide room.
Haven’t heard the Voltis but they might be a good option since you’re coming from the B&W sound.
The Spatial Audio M5 Sapphire is another you should consider. Spatials have a sound that falls somewhere between an planar-magnetic panel and a conventional box speaker. Not as much soundstage depth and not quite as transparent as Maggies but they’re higher in detail and bass extends lower. Good tweeters in the Spatials, the quality level of which are typically found only in >$6K/pair speakers.
