The upper curves show the effect of the 'bass tilt' control on the free
field response. The lower curves show the effect of the 'treble tilt' and
'bass roll-off' controls.

DRIVERS
The bass frequencies are repro-
duced by a 250 mm (10") bass
driver loaded by a 24 litre vented
box. The -3 dB point is 40 Hz and
the low frequency response ex-
tends down to 36 Hz.
The high frequency driver is a 25
mm (1") metal dome, with pistonic
behavior upto 23 kHz, is loaded by
a proprietary DCW. Both drivers
are magnetically shielded for appli-
cations where the stray magnetic
field must be minimized.
CROSSOVER FILTERS
The crossover frequency of the
active crossover is 1.8 kHz. In
order to obtain uniform frequency
balance in differing acoustic condi-
tions, special calibrated controls
are included in the crossover. Three
such controls are at the users dis-
position including treble and bass
tilt, and bass roll-off switch. Each of
these controls allow for adjustment
in 2 dB increments and also pro-
vide the possibility of muting the
channel for test purposes. A high
pass filter is included in the LF
channel to protect the woofer from
subsonic signals. The crossover
network is driven by an active bal-
anced input stage. Variable input
sensitivity allows for accurate level
matching to the mixing console.
The tweeter driver is mounted in a
DCW to match the dispersion
characteristics to that of the bass
driver. The DCW may be rotated
for horizontal or vertical mounting.
DCW TECHNOLOGY
The revolutionary Directivity Con-
trol Waveguide Technology is a
means of greatly improving the
performance of a direct radiating
multiway loudspeaker under nor-
mal listening conditions. The basic
idea is to match the different drive
units precisely, in terms of both
frequency response and directiv-
ity. This will result in a smoother
and virtually uncoloured off-axis
system response. Also, due to im-
proved directivity control, especially
in the midrange frequencies, more
direct sound and less early bound-
ary reflections are received at the
listening position. This gives im-
proved stereo imaging and ensures
the system is less sensitive to dif-
fering control room acoustics than
any conventional direct radiator de-
sign. The DCW Technology im-
proves the drive unit sensitivity by
