TANNOY VQ40DF Line Array Speaker ลำโพงแขวน ไลน์อาร์เรย์
The VQ 40DF (Down Firing) is a dedicated two way down-firing Mid/High loudspeaker designed to seamlessly integrate with the VQ full range loudspeakers (and VQ MB and VS 15DR LF devices) matching their exact footprint. 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 & 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.
Features :
- 135 dB Maximum SPL (Average)
- Tightly controlled 40 degree conical dispersion for long-throw applications
- Patented PSW™ Waveguide technology for class-leading directivity
- High performance 2-way Mid-High down-firing device
- Modular design for down-fill on larger clusters
- Excellent Phase Coherence
- Perfect time alignment without the associated problems of multi source interference
- Compact Dimensions
- Extremely high sensitivity, therefore high SPL’s can be achieved with a very modest amount of amplifier power
- Exceptional transient response
Applications :
- Auditoria / Lecture Theatres
- Corporate AV
- Houses Of Worship
- Live Music / Performance Venues
- Night Club
- Performing Arts Spaces
- Portable PA
- Sports Arenas / Stadia
- Theme Parks
