SERIES
Congratulations on the purchase of your new VQ loudspeaker. You now own one of the finest professional audio
products available. Performance of your VQ loudspeaker in terms of accuracy & perceptive sound quality is
second to none as you will discover. The VQ series of products was developed to provide the sound
reinforcement system designer with essential tools for creating loudspeaker systems with exceptional pattern
control and high output. This series provides an array of devices ideally suited to a variety of live sound
reinforcement and high level foreground music venues.
Please read this user manual to get the optimum performance from your new VQ loudspeaker system.
1 INTRODUCTION
The VQ full range products utilize a unique driver technology to radiate a coherent single point source for superior
dispersion control when coupled to our single horn. This advanced design aligns the acoustical centres of the
transducers providing a single coherent wavefront emanating from the throat.
The driver uses two concentric annular ring diaphragms. The larger of the two has a 3.5” voice coil and reproduces
frequencies from 400Hz to 7 kHz. Another major advantage here is that there is no crossover anywhere near the
vocal region ensuring the most natural and phase coherent reproduction at this critical area. The 2” HF diaphragm
takes over at 7kHz to 22kHz by way of a passive or an active crossover. The external casting features extensive
heatsinking ensuring good heat transfer for high power handling and very low power compression.
The VQ 60
is a full range, three-way loudspeaker system designed for applications which
require very high output capability with class leading pattern control. The VQ 60 is
perfectly suited for use in arrays or singly in demanding high SPL music or speech
applications. Unlike line array solutions, the VQ 60 can produce enough power and clarity
to be used individually maintaining your building's aesthetics. With low frequency
extension to 90Hz, the VQ 60 can be combined with various subwoofers for extended
bandwidth. The VQ 60 can be configured for use in Bi-Amp or Tri-Amp mode, in
conjunction with a suitable digital signal processor (DSP).
The VQ 100
is a full range, three-way loudspeaker system designed for applications which
require high output capability with class leading pattern control. The VQ 100 features a
wide and exceptionally well defined dispersion characteristic.For a variety of uses, a single
VQ 100 can produce more power and clarity over itʼs 100 degree beamwidth area than
many arrayed solutions using multiple cabinets. With low frequency extension to 90Hz,
the VQ 100 can be combined with various subwoofers for extended bandwidth. The
VQ 100 can be configured for use in Bi-Amp or Tri-Amp mode, in conjunction with a
suitable digital signal processor (DSP).
The VQ DF
(Down Fill) is a dedicated two way down-firing Mid/High loudspeaker designed
to seamlessly integrate with the VQ full range and VQ MB loudspeakers matching their
exact footprint. The down firing configuration allows the VQ DF to be tight packed without
the need for any complex fly-ware. With a coverage pattern of 80 x 50 degrees, the VQ DF
will provide even coverage to the areas immediately below the main flown loudspeakers.
For full range use the VQ DF can also be used along with the VQ MB.The VQ DF can be
configured for use in Single or Bi-Amp mode, in conjunction with a suitable digital signal
processor (DSP).
The VQ MB
duplicates the low frequency performance of the VQ 60 & VQ 100 full range
loudspeakers, it is intended for use as a flown or ground stacked, high power low/mid
frequency module used in conjunction with full range or mid/high systems in the VQ series.
Two (12 in) low frequency transducers, offer high power handling and low power
compression for high continuous SPL capability. A newly designed LF loading design
provides the highest possible sensitivity for low/mid frequency output (105dB/w). The
VQ 60 and VQ 100 provide consistent beamwidth down to about 500Hz. This usually is
sufficient for many applications, but often the situation calls for extended vertical pattern
control for additional gain before feedback in the lower midrange to mid-bass region and/or
improved direct-to-reverberant ratio in the mid-bass range for live rooms. The addition of
one or more VQ MB devices to the array will extend the vertical pattern down to the
250Hz range and lower by taking advantage of the basic acoustical principles of
spaced sources.
