The down firing configuration allows the VQ 40DF to be tightly packed without the need for any complex fly-ware. With a conical 40 degree coverage pattern, the VQ 40DF will provide even coverage to the areas immediately below the main flown loudspeakers. For full range use the VQ 40DF can also be used along with the VQ MB or VS 15DR.

The VQ 40DF can be configured for use in Single-way or Bi-Amp mode, in conjunction with a suitable digital signal processor (DSP). 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 and sound quality is second to none. The VQ horn design principles provide definitive 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.
