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.

TOA SR-A Series Mid-Size Line Arrays feature TOAʼs proprietary "Synch-Drive" horn technology (pat. pending) to provide a uniform, high frequency sound field offering excellent sound clarity and minimal interference. Mid-high modules include the SR-A12L (long-throw) and the SR-A12S (short-throw) each with dual compression drivers and 12" low frequency driver. The SR-A18 subwoofer module features a heavy duty 18" low frequency driver rated at 720 Watts continuous power handling. Along with weather resistant models and multiple mounting hardware options, the SR-A Series Line Arrays are backed with a five year product warranty. | FEATURES: | - Designed for wide bandwidth response - These compact and powerful 2-way modular speaker units can be used in multiple configurations as required to deliver greater output power with a more extended frequency response.
- High-performance driver units - Each Type A Series speaker module contains a 30cm (12“) low frequency unit and a high-frequency horn attached to two compression drivers for greater output.
- Wavefront control - The horn incorporates a proprietary phase wavefront control throat that functions to obtain the best possible performance from the high frequency drivers.
- Adjustable sound coverage - Type A Series provides two speaker configurations designed for specific coverage characteristics, each having a different taper. The 5-degree taper is for effectively transmitting sound over distance while the 15-degree taper is optimized for excellent short range coverage.
- Simple maintenance - Maintenance and servicing are made easier on the Type A Series to suit it for permanent installations. All driver replacement is possible from the speaker's rear, a simple and speedy procedure.
- SR-A12L Long-throw enclosure (15°V x 90°H)
- SR-A12S Short-throw enclosure (5°V x 90°H)
- Components: Dual compression drivers. 12” low frequency driver. Power handling: 450 W (LF), 180 W (HF)
