Overview
The AVANDA 28A is a compact, dual 8” two-way active line array system engineered for high-performance sound reinforcement in small to medium-scale applications and premium fixed installations. Delivering exceptional clarity and power, it is designed to meet the rigorous demands of professional audio environments, both indoors and outdoors.
Featuring innovative ARROWHEAD™ waveguide technology, the AVANDA 28A achieves precise vertical directivity in the high-frequency range for superior sonic detail. An integrated 90° horn ensures consistent horizontal coverage, delivering a smooth, uniform sound field across the entire listening area. Built-in DSP provides sophisticated system management, allowing for seamless integration and peak performance in any venue.
The enclosure is CNC-machined from premium birch plywood for maximum structural integrity. To ensure longevity in challenging environments, it is finished with a high-durability polyurea coating—offering excellent waterproof, wear-resistant, and high-temperature properties.
