Jabra PanaCast 50 video bar system
The HORIZON VHA 118.2SA Processed Active Subwoofer is engineered for high-performance audio in larger venues, delivering an exceptional sound pressure level relative to its size. Featuring a robust 18-inch B&C woofer housed in a bass reflex enclosure constructed from birch plywood, the VHA 118.2SA incorporates a laminar airflow system that enhances acoustic performance. Powered by a 2500-watt Class-D amplifier, it offers six newly developed DSP preset configurations for greater flexibility across applications. The subwoofer’s design has been refined using BEM finite element modelling to optimise the internal load volume, while improvements to the grille and protective mesh have reduced acoustic resistance, resulting in superior output. The HORIZON VHA 118.2SA extends the system’s low-frequency response down to 30 Hz and supports fully ground-stacked arrays using integrated hardware. This model represents a significant advancement in subwoofer efficiency and is well-suited for demanding professional audio environments where reliability and power are essential.
The HORIZON VHA 118.2SA is a processed active subwoofer specifically developed to enhance low-frequency performance in professional audio applications requiring high sound pressure levels and reliability. Built for use in expansive indoor or outdoor environments, this subwoofer is engineered to provide consistent, high-output bass reinforcement when deployed in ground-stacked array configurations. Central to its design is a single 18-inch B&C woofer, housed within a robust birch plywood enclosure featuring a bass reflex configuration with optimised laminar airflow.
With an integrated 2500-watt Class-D amplifier, the HORIZON VHA 118.2SA offers six revised DSP presets, allowing precise control and adaptability across various deployment scenarios. The subwoofer benefits from acoustic improvements achieved through finite element simulations (BEM), which optimise internal load volume while reducing impedance caused by the grille and protective mesh. This results in enhanced SPL output, system efficiency, and sonic accuracy.
The HORIZON VHA 118.2SA significantly extends system frequency response down to 30 Hz, making it a crucial component in large-format line array systems where extended low-end performance is essential. Integrated mounting hardware further supports modular stacking in complex audio setups, offering system designers increased flexibility. Its rugged construction and high-performance characteristics make it well-suited to touring professionals, rental companies, and fixed installations in arenas, theatres, and outdoor venues requiring consistent low-frequency reinforcement.
