  • Introduction
  • Specification

The LA-4240B is a compact line array speaker designed for both speech and music, featuring four 4” full-range drivers. Complementing it, the LA-150SUB is an active subwoofer with a high-power 15” woofer and advanced digital signal processing, delivering outstanding audio performance with remarkable output stability.


For enhanced portability, the full-range speakers can be detached and conveniently stored within the bass reflex port of the subwoofer, optimizing space efficiency.


When used together, a setup of two LA-4240B speakers and one LA-150SUB subwoofer produces crisp, dynamic sound with deep bass, achieving a high sound pressure level that exceeds comparable systems. Its superior outdoor projection and easy installation make it well-suited for a variety of locations, such as churches, museums, live performance venues, transportation hubs, sports arenas, government buildings, conference spaces, lecture theaters, shopping centers, and AV demonstration rooms.
