The VQ 85DF (Down Firing) Mid/High loudspeaker is designed to seamlessly integrate with the VQ full range and VQ MB loudspeakers and match their exact footprint. The down firing configuration allows the VQ 85DF to be tight packed without the need for any complex fly-ware. With a coverage pattern of 80 x 50 degrees, the VQ 85DF will provide even coverage to the areas immediately below the main flown loudspeakers. For full range use the VQ 85DF can also be used along with the VQ MB. The VQ 85DF can be configured for use in Single or Bi-Amp mode, in conjunction with a suitable digital signal processor (DSP).
