Howdy! been thinking a lot lately about changing my speakers out which are the original Nola Boxers. don't get me wrong, these are very good and have enjoyed them for 4+ years but.....the Sierra 2's have me intrigued especially because of the RAAL tweeter. I can listen to the Boxers for hours on end with no ear bleeding, forward and in your face sound. they also sound very good off axis and even if we're sitting in another room. so how would you say the Sierra 2's would compare? my room size is 20' x 14' with a 10' ceiling and is open to a 6 ft. wide hallway that also goes to our kitchen & living room via open walkways. basically, an open floor plan. I have the Primare i30 integrated which is 100w-8 ohms and 180w-4 ohms. I also have one Rythmik L12 sub. thanks for any info.
