Product Description
The VQ 40DF (40x40), is a very high output down ring Mid/High loudspeaker systems
designed for applications requiring high impact sound reinforcement with class leading
pattern control.
The modular design approach allows the sound system designer to create seamless
andpredictable arrays, or they can be used singly as part of large distributed systems.
VQ 40DF addresses the requirement for compact dimensions without compromising
performance in any way.
VQ MH elements which are available in various patterns will integrate seamlessly with
the VQ 40DF enclosures to facilitate tight pack arrays; the compound angles on the
enclosure avoid unsightly spaces between separate cabinets when arrayed horizontally
VQ MB or VS 15DR elements can be added to extend bandwidth and pattern control to
lower frequencies.
The VQ 40DF can be congured for use in Single-Amp or Bi-Amp mode, in conjunction
with a suitable digital signal processor (DSP).
Horn design involves balancing compromise…..until now.
Our unique approach in keeping what is effectively a Dual Concentric behind a single
horn gives us many performance advantages. Performance of the VQ 40DF in terms
of accuracy & sound quality is second to none. The VQ horn design principles provide
denitive and measurable advantages over multiple-horn and co-axial designs.
Each VQ 40DF incorporates a unique driver technology to radiate a coherent single
point source for superior dispersion control when coupled to a PSW™ (Point Source
Waveguide). This advanced design aligns the acoustical centres of the transducers
providing a single coherent wavefront emanating from the throat. The PSW™
waveguide achieves an optimum balance of extremely well controlled coverage, smooth
frequency response, and natural sound character.
For outdoor applications, weather resistant enclosures which incorporate stainless steel
hardware are available.
