Overview Specifications Brochure Related Products Solutions Latest News & Cases

The LA-4241B is a compact line array loudspeaker that houses four 4-inch full-range drivers and is well-suited for both vocal and musical reproduction. Complementing it is the LA-180SUB, an active subwoofer that integrates advanced digital signal processing, a robust 18-inch woofer, and a high-output amplifier module to deliver powerful, reliable low-frequency performance.

For enhanced portability, the full-range units can be disconnected and conveniently stored within the subwoofer’s bass reflex port, significantly reducing the system’s overall footprint during transport.

When deployed as a complete system—comprising three LA-4241B units paired with one LA-180SUB—the setup produces articulate, vibrant audio with extended bass response. The system features straightforward installation, achieves high SPL capabilities, and offers output performance that outperforms many competing solutions. Its impressive throw distance makes it especially effective in outdoor environments, while remaining highly adaptable across a broad spectrum of venues, including houses of worship, museums, live music stages, transit hubs, sports arenas, government halls, conference centers, lecture theaters, retail spaces, and AV demonstration rooms.
