Bowers & Wilkins CT8XO MK2 Installation And Setup Manual page 7

CT8 LR
A 3-way speaker intended for front left and right channels,
one placed in vertical orientation at each side of the
screen.
CT8 DS A full range surround speaker that may operate in either
2-way dipole or 3-way monopole mode.
CT8 CC A 3-way centre channel speaker that is acoustically
similar to the CT8 LR, but designed with a more
symmetrical drive unit layout so that it may be used in
horizontal orientation immediately above or below the
screen.
CT8 SW A subwoofer that may be added to any or all the above
three models to extend their bass response well below
the accepted lower limit on human hearing.
CT8 XO Mk2 An active, line-level crossover/equaliser that:
a) is required for each CT8 LR, CT8 CC and CT8 DS
and must be configured to the particular speaker
type.
b) provides active filtering between midrange and
bass drivers and between bass drivers and
CT8 SW (if used).
c) controls whether a surround speaker operates in
dipole or monopole mode and, in dipole mode,
controls the direction of the positive and negative
polarity lobes.
d) provides high- and low-frequency level control,
plus three adjustable parametric equalisers to
adjust for speaker/room interferance effects.
