Constructed in birch plywood with a tough and tour-ready synthetic rubber surround, each VHA406A comprises four 6.5-inch woofers plus a 1.4” large-format neodymium compression driver with a 2.5” voice coil. The purpose-designed central waveguide, optimised with BEM finite element simulations, offers dispersion of 90° horizontal and 20° vertical, with precise and focused vertical control across the enclosure’s entire operating range. The result is a combination of perfectly balanced, symmetrical dispersion – multiple system can be coupled with full coherence far beyond 18KHz, plus a particularly powerful, defined midrange with a frequency response extending from 65Hz to 20KHz.
The VHA406A’s Class-D, switch mode amplifier module is constructed in die-cast aluminium with natural convection to deliver 600W for the LF section and 300W for the HF. Courtesy of an integrated DSP processor with next generation algorithms, users can choose from eight presets to further tailor system performance whilst enjoying the system’s tremendous headroom to ensure the best possible audio fidelity.
Integrated hardware allows the linking of up to six VHA406A cabinets with variable angles from 5° to 20° (in 5° steps), ensuring an easy and error-proof system configuration and set-up. Rigging is simplified even further by the inclusion of only one setting point per side. All setting pins are fixed and integrated into the hardware, eliminating both the risk of loss and damage in transport.
Crucially, the HORIZON VHA system also boasts integrated quick-release anchor points that facilitate the creation of horizontal arrays using the dedicated flybar. Each flybar will support up to three VHA406A cabinets, while multiple flybars can be joined for the creation of arrays delivering up to 360° coverage.
