The LA-4240 is a compact line-array element featuring a 4.5-inch full-range driver, engineered to deliver balanced reproduction for both speech and music. The LA-15SUB is an actively powered subwoofer equipped with onboard digital signal processing and a precision-tuned 15-inch woofer, optimized for high-output performance and superior sonic accuracy. When deployed as a dedicated cluster comprising two LA-4240 units and one LA-15SUB, the system offers articulate high-frequency clarity, robust low-end extension, straightforward and time-efficient rigging, and a maximum SPL that substantially exceeds that of comparable solutions in its class. Its exceptional throw capability makes it well suited for demanding acoustic environments, including houses of worship, museum installations, live sound reinforcement, transit hubs, sports venues, government chambers, corporate boardrooms, lecture halls, retail spaces, and audiovisual demonstration facilities.
