They're a little like the old RS1's, they're livelier in the treble than the RX2's. How their midrange will perform will rely on their positioning in the room they'll be used in - the closer the speaker is to the wall the stronger the bass will be, which in turn will usually overpower the midrange and treble. Bringing them further out will weaken the bass and bring the treble and midrange more to the foreground.
