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.
The CDM 7NT is a floorstanding loudspeaker, exquisitely finished in a choice of real wood veneers. The extra volume and drive unit gives an extended bass response. Technological features include Nautilus tweeter, Kevlar® mid/bass driver, bass radiator with mushroom construction dustcap and Flowport.
