Even within a version, the components and sonics can change. See the 2CE Stereophile review, page 2:

The 2CE (I think I may have had the early version!)goes pretty low and in my small room it overloaded the room with bass. Dynamics were just okay...don't expect horn/PA speaker dynamics...although this is true with most speakers. I think they will go loud enough for most users and provide a balanced sound when used in a big room, albeit a bit lacking in transparency and detail. Not a bad thing with some music.
