User manual B&W SCM 8

[. . . ] They are dipoles, projecting sound along two opposing axes with opposite polarity. [. . . ] The resulting cancellation between those opposing phase responses means that the sound level projected at right angles to these axes (in the null plane) is much lower in level. q The reason for this is the desirable non-localisation of the surround sound. The speakers are positioned at each side of the listener with the null plane pointing towards the listening area, this means that the vast proportion of the sound is reflected by the room surfaces and is diffuse in nature. q A further advantage of the Home THX® approach is that there is a seamless transition between the front and surround sound fields that is independent of the relative position of the speakers - and a wider spread of listeners can hear the overall sound field. q The triangular construction of these speakers has several advantages, functional as well as aesthetic. Thirdly, the triangular shape also reduces the levels of standing waves inside the cabinet which can re-radiate as coloration. Technical highlights Kevlar®: B&W developed and patented the method of using Kevlar® for loudspeaker cones to reduce unwanted standing waves.
