Re: How's the midrange on Sierra-2?
True, the RAAL produces incredibly detailed, airy & smooth highs, while the SEAS woofer produces awesome bass. They deserve all the praise given to them. Not sure why you could not find anything talking about the midrange. Let me assure you: The mids are among the best I've heard from a 2-way bookshelf speaker, even embarrassing many floorstanding models despite their cost. The -2's mids have been compared to the Ascend RAAL towers, which have a dedicated midrange driver, like this: The towers put you in the front row, while the Sierra-2's put you in the 2nd or 3rd row of the venue.
I have not heard the towers, but my -2's put the performers in the room. From highs to lows this is a balanced speaker.
