The CT 800 range comprises five products:
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 of human hearing.
CT8 XO 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 interface effects.
The crossover between midrange and tweeter drive units is accomplished by a passive filter inside each speaker.
