The CDM 1NT builds on the success of the CDM1 SE product, which received countless awards for sonic excellence, build quality and overall performance. The cabinet is exquisitely finished in real wood veneers, and is skillfully fashioned to produce the graceful curves and contours that actually seek to reduce resonances and enhance clarity of sound. 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.
