The LD Systems MAUI 66 G3 is a flagship, fully active 4-way cardioid column PA system designed for professional DJs, bands, live performances, and event production. Delivering 3,800W peak power and a maximum SPL of 135 dB, it combines powerful full-range sound with an extended-range column and controlled dispersion. Its integrated design offers substantial headroom, streamlined setup, and professional sound reinforcement for demanding indoor and outdoor applications.

The two-piece column houses 16 × 3.5-inch neodymium midrange drivers and four 1-inch compression drivers. Two midrange drivers are positioned above the high-frequency section to extend the system's reach and help maintain midrange clarity in open-air applications. BEM-optimized waveguides, specially developed phase plugs, and horn-loaded midrange drivers contribute to efficient sound projection and coherent mid- and high-frequency reproduction. The system provides a nominal dispersion pattern of 120° horizontally by 25° vertically.

The passive cardioid column design directs sound toward the audience while reducing rearward radiation by up to 18 dB. When paired with an additional MAUI 66 G3 subwoofer facing rearward and configured with the Cardioid preset, the cardioid principle can also be extended into the low-frequency range. Alternatively, a forward-facing second subwoofer can increase low-frequency sound pressure by up to 6 dB under the specified configuration.
