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
behaviorupto23kHz,isloadedby
a proprietary DCW. Both drivers
aremagneticallyshieldedforappli-
cations where the stray magnetic
field must be minimized.
CROSSOVERFILTERS
The crossover frequency of the
active crossover is 1.8 kHz. In
order to obtain uniform frequency
balanceindifferingacousticcondi-
tions, special calibrated controls
areincludedinthecrossover.Three
such controls are at the users dis-
positionincluding treble and bass
tilt,andbassroll-offswitch.Eachof
thesecontrolsallowforadjustment
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
channeltoprotectthewooferfrom
subsonic signals. The crossover
networkis driven by an active bal-
anced input stage. Variable input
sensitivityallowsforaccuratelevel
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
forhorizontal orverticalmounting.
DCWTECHNOLOGY
The revolutionary Directivity Con-
trol Waveguide Technology is a
means of greatly improving the
performance of a direct radiating
multiway loudspeaker under nor-
mallisteningconditions.Thebasic
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-
proveddirectivitycontrol,especially
inthemidrangefrequencies,more

ary reflections are received at the
