The LA-4241B is a compact linear array speaker with four 4” full-range drivers, engineered for both speech and music reinforcement. Complementing it, the LA-180SUB is an active subwoofer that integrates advanced digital signal processing, a robust 18” woofer, and a high-power amplifier module to ensure powerful output and consistent audio performance.
For greater portability, the full-range speakers can be detached and conveniently stored within the subwoofer’s bass reflex port, streamlining transport and setup.
When combined, two LA-4241B speakers and one LA-180SUB subwoofer produce crisp, dynamic sound with rich bass, delivering a high sound pressure level that outperforms comparable systems. With exceptional outdoor projection and effortless installation, this system is an excellent choice for diverse venues, including churches, museums, live events, transportation hubs, sports arenas, government buildings, conference spaces, lecture halls, shopping centers, and AV demonstration rooms.
