The CDM 9NT is the largest floorstander in the range producing generous bass extension and delivering a tight midrange. The CDM 9NT incorporates the unique surroundless midrange FST first pioneered in the 800 Series. Technological features include Nautilus tweeter, braced cabinet construction, Flowport and mushroom dust cap for improved bass throw. ● The handcrafted cabinets in real wood finishes incorporate the best in design know- how; the styling and contouring is truly a triumph in the collaboration between science and nature. Technical highlights Tweeter on top: B&W's Tweeter on top technology ensures that the sound remains focused and time-sensitive and that the stereo-image is presented with unparalleled three dimensional accuracy. Kevlar®: B&W developed and patented the method of using Kevlar® for loudspeaker cones to reduce unwanted standing waves. DuPont originally created Kevlar® for use in bulletproof vests. Flowport™: Golf ball aerodynamics theory points the way towards lower distortion reflex ports. Dimples improve the way the air flows over the surface of any object. In the case of reflex ports, they offer a significant improvement over simply flaring the port ends in reducing air flow turbulence at each end of the port; so you get less chuffing noise and less compression at high sound levels.
