LD Systems VA4 Line Array Speaker
The LD Systems VA4 is a lightweight, ultra compact 2 x 4" line array speaker cabinet for configurations with an 80Hz – 19kHz frequency response. The dual 4" woofers with high efficiency neodymium magnets and Kevlar cones have a power handling capacity of 200W continuous and 400W peak. Coupled to a 1" waveguide, the neodymium high frequency compression driver features a 1.35" voice coil, protection circuit and a 75W continuous/150W peak rating. Individual element dispersion is 120° x 10° over a wide frequency range.
The VA4 cabinet is made from 12mm birch ply painted in hard-wearing, water-resistant Dura-Coat LX. It is equipped with Neutrik NL-4 connectors, rigging hardware and easy angle adjustment from 0° to 7.5° in three 2.5° steps. The VA4 is designed both for flying and ground stack applications.
For low frequency extension the dual 12" Bandpass subwoofer V212B and the V215B 2x15” Bass reflex subwoofer perfectly complement the VA4. Ease GLL-files and controller setups for the LD Systems DPA260 are available online for optimum array configuration and easy startup.
