I think B&W has gone downhill in their crossover design in the current line. This is partially because they changed the way the make them. In many cases they mass produce them on separate circuit boards and then plug them in. They use to make them indivdually in each speaker. This helps production in larger quantities; but it looses something in changing how they traditionally designed them. They are a victim of their own success I guess.
One of my systems has a pair of the original CDM-1. It has a first-order crossover not found in the CDM-1SE or CDM-1NT. I have heard the newer versions and they are not quite as musical. They probably work better for HT though. The original CDM-1 was the one that won all the audio awards including Loudspeaker of the year in Europe, but they don't tell you that in their marketing materials; they make it sound like the current models are award winning.
