tweek,
i suggest emailing brian cheney directly; he's quite forthright w/his responses.
i would suspect that in this case, the added quantity of drivers allows a higher spl w/less distortion - not an issue in small-to-medium rooms, perhaps, but mebbe a consideration w/large rooms. also, higher efficiency means more tube-friendly.
regarding the rm40 specifically, comparing it w/its smaller siblings that share the same midrange & tweet, the rm40 offers the adwantage of being a line-array set-up, which is usually beneficial for soundstage, as room interactions are less problematic, due to the same response coming from both the top and the bottom of the speaker, & ear-height is usually less critical...
hth,
