SCM 8 - THX Home Cinema Series
In very good condition
● The Surround Cinema Monitors have a unique appearance and design. 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.
● 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.
● 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.
● The triangular construction of these speakers has several advantages, functional as well as
aesthetic. Firstly the back-to-back distance between the drive units widens the dipole null
area and permits greater numbers of listeners to experience the dispersive nature of the
sound. Secondly the speakers are mounted higher than the listeners and the sloping faces
project the sound away from them, giving them a wider null area and a better illusion of
height. Thirdly, the triangular shape also reduces the levels of standing waves inside the
cabinet which can re-radiate as coloration.
MatrixTM: The basic construction of nearly all loudspeakers is exactly the same -
panels of wood-based materials, bonded to form a rectangular box. B&W
studied and evaluated how each aspect of cabinet behaviour and the efficiency
of various materials and construction methods affects sound.
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.
