The B&W CM series falls between the higher-end 700 series and lower-end 600 series. New to the line are the floorstanding CM7 ($900/each) and stand-mount CM1 ($450/each). They'll be available in 30 days. Already out is the CMC center ($600). Inside the wood-veneer enclosure is B&W's famous tube-loaded tweeter, which gives the much higher-priced Nautilus line its extraordinarily clean and revealing high frequency extension.
