VOICE LINE VL8
The Voice Line VL8 is a unique professional column
line array loudspeaker providing high fidelity sound
reinforcement with a wide cylindrical wave pattern.
A true line array source, it performs remarkably in venues
with poor acoustics and dramatically reduces unwanted
feedback during live performances.
The Voice Line VL8 was designed to perform to strict
acoustic parameters. Critical in the design is the high
frequency waveguide. Typical column line arrays entrust
the high frequency reproduction to the cone drivers.
While this fulfils the SPL requirement, it almost always
fails to meet the necessary frequency extension required to
generate cylindrical waves at high frequencies.
The innovative waveguide utilises 8 identical 1” custom
tweeters coupled to a fibre reinforced waveguide which, in
conjunction with the robust 3” mid-range drivers, produces
impressive frequency bandwidth and true cylindrical waves.
What this means is that for every doubling of distance, the
sound pressure level drops
by just 3dB, not 6dB as with conventional speaker systems.
This ensures uniform coverage in the horizontal span
of 110º.
The Voice Line VL8 enclosure is fabricated from 5mm solid
extruded aluminium with die-cast end caps. The rigidity
provided ensures cabinet resonance is minimised and
there are no spurious noises or unwanted colouration.
The front grille blends with the slender aluminium
enclosure providing an attractive architecturally pleasing
result. Speaker colours include black (VL8B) or white
(VL8W) and several mounting options are available
including fixed, variable angle and pole mounted brackets.
The Voice Line VL8 provides both direct voice-coil and
constant voltage operation via a rear panel selection
switch.
