WLA-28
WLA-28 is a dual 8″ line array element designed for touring and installation environments that demand clarity, output and consistent performance. Engineered for versatility and reliability, it delivers a balanced combination of power, coverage and control for scalable professional systems.
It features two 8″ LF drivers paired with a 3.2″ HF compression driver, delivering strong low-frequency response and detailed high-frequency reproduction. With a maximum SPL of 132 dB, the system provides ample headroom for high-output applications while maintaining clarity across the full frequency range.
Constructed from 15 mm birch plywood, the enclosure is built for durability in demanding rental and touring environments. Integral side plate adjustable rigging allows secure and flexible deployment, supporting a wide range of flown array configurations.
