Two different speakers. The Revel are more traditional while the BMRs have specifically designed in a wide dispersion. Adding a half decent sub to the BMRs should get you speakers that will do most anything. Of course when I say that someone jumps on the thread and says BUT the BMRs don't play all day at 120db in testing. That is an abnormal requirement for probably less than 1% of all audio geeks. I personally would listen or try the BMRs and if they work buy them! If not you can always back track to the Revels. In reality both the BMRs and Revels are very nice speakers.
