ตู้ลำโพงแขวน Point Source TANNOY VQ 64DF 2 ทาง 800 วัตต์ Dual Concentric 3.5 “และ 1.75” สำหรับการสร้างเสียงกลางและความถี่สูง จากยี่ห้อ TANNOY
VQ 64DF
The modular design approach of the VQ 64DF allows the system designer to create seamless and very predictable arrays which are ‘tight packed’ to avoid any unsightly spaces between cabinets; or they can be used singly as part of large distributed systems. The VQ 64DF addresses this requirement for compact dimensions without compromising performance in any way.
With the addition of these VQ products it is now possible to design and install arrayed configurations comprising of multiple MH (mid-high) horns and DF (down firing) horns, along with MB (mid bass) enclosures – ideal for applications such as large sports arenas and stadia.
Comprehensive Installation Package
The VQ 64DF can be configured for use in Single-Amp or Bi-Amp mode, in conjunction with a Lake LM26/44 digital signal processor (DSP) or Lab Gruppen PLM+ or D series platforms.
Exceptional Sound and Reliability
Our unique approach in keeping what is effectively a Dual Concentric behind a single horn gives us many performance advantages. Performance of the VQ 64DF 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.
The VQ 64DF 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.
