FBT VHA 406A

With optimal audience coverage and the ability to adapt to project requirements, HORIZON VHA represents a breakthrough in flexible sound reinforcement technology with exceptional sound quality. Made in Italy with the uncompromising manufacturing excellence for which FBT is renowned, the HORIZON VHA series includes the full VHA406A range, plus two low-frequency extension options in the form of the 12-inch VHA112SA and 18-inch VHA118SA.

Constructed of birch plywood with a sturdy synthetic rubber surround, each VHA406A features four 6.5-inch woofers and a 1.4-inch large-format neodymium compression driver with a 2.5-inch voice coil. The specially designed center waveguide, optimized through BEM finite element simulations, provides 90° horizontal dispersion and 20° vertical dispersion, with precise and focused vertical control over the speaker's entire operating range. The result is a perfectly balanced and symmetrical dispersion combination: the multiple system can be coupled with full coherence well beyond 18KHz, as well as a particularly powerful and defined midrange with a frequency response extending from 65Hz to 20KHz.

The VHA406A's switchable Class D amplifier module is constructed of natural convection die-cast aluminum to deliver 600 W for the LF section and 300 W for the HF section. Thanks to a
