They will be palced in a 20x27' room. Power will come from an all Bryston front end including the all new 4B SST squared. Music is a mix of classic rock and jazz. I tend to value bass slam and depth as well as the ability to disappear. Coherence is also important.From a theoretical standpoint (I've heard the Sophias, not the Revels), for a room that size the Revels have a big advantage on moving more air with their multiple drivers. They have nearly double the radiating surface of the Sophias (198 sq. in. vs. 117). The Revels should have more bass slam for classic rock; either will do well for jazz; the Revels would have an advantage on big band jazz.
The Sophias are well known for disappearing and having good coherence. OTOH, when the room gets too big, *any* speaker loses its ability to disappear, and you become more aware that the sound is emanating from two appliances trying to fill the space. Both speakers are known for good coherence. The Sophia is sort of time-aligned.
The Revel makes no pretense of time-alignment, but I have the S'phile review of the Revel by Larry Greenhill, who's been reviewing high-zoot speakers for decades, and his summary stated that the Revel Salon 2 is the best sounding speaker he's ever had in his house, and that it sounds particularly coherent.
