Hi. I have auditioned them twice at AES New York 2015 and 2017. I would say that they are very good. There is a small thing. Im not sure if they are "as musical" as the predecessors. 2242 and 2245, but for power and "correctness" they are fantastic. The new sub 15 is also very good. I might get a pair at a later point, but for now im content with a pair of 4645C
