LD Systems Maui 66 G3
(LD Systems Maui-66-G3)
Powered Cardioid Column PA System
The LD Systems MAUI 66 G3 is a high-performance, fully active 4-way column PA system with a passive cardioid column design, engineered for powerful sound reinforcement and extended audience coverage. Delivering 3800W peak power and a maximum output of 135 dB SPL, it combines an 18-inch neodymium subwoofer, 16 midrange drivers, and four high-frequency compression drivers for deep bass, clear vocals, and detailed sound reproduction. Featuring DynX Gen. 2 DSP, Bluetooth 5.4 audio streaming, and cable-free column assembly, this system provides professional audio performance for DJs, live bands, outdoor events, and demanding sound reinforcement applications.
LD Systems MAUI 66 G3 Competitive Differences

LD Systems MAUI 66 G3 Description
The LD Systems MAUI 66 G3 combines powerful amplification with advanced acoustic engineering to deliver full-range sound across large listening areas. Its custom 18-inch neodymium woofer features a 4-inch voice coil and a low-tuned bass-reflex enclosure with elliptical, airflow-optimized ports that minimize turbulence and unwanted port noise. The two-piece column houses 16 custom 3.5-inch neodymium midrange drivers and four 1-inch neodymium compression drivers. Two additional midrange drivers positioned above the high-frequency section help extend vocal clarity and midrange projection over longer distances, making the system suitable for outdoor performances and larger event spaces.
The system's passive cardioid column directs sound energy toward the audience while reducing rearward radiation by up to 18 dB across the 100 Hz to 1 kHz frequency range. Its 120° horizontal by 25° vertical dispersion pattern provides broad audience coverage while controlling unnecessary vertical sound spread. Horn-loaded midrange drivers, BEM-optimized waveguides, and newly developed phase plugs improve efficiency, wavefront coherence, and consistent sound distribution. The fully active Class-D amplifier delivers 1900W RMS and 3800W peak power, supporting a maximum SPL of 135 dB. DynX DSP Generation 2 incorporates advanced peak, RMS, and thermal limiting, while crossover frequencies at 200 Hz, 700 Hz, and 1800 Hz optimize the system's four-way operation.
For applications requiring even greater low-frequency performance, the MAUI 66 G3 can be expanded with an optional MAUI 66 G3 SUB. Positioning the additional subwoofer facing forward can increase low-frequency output by up to 6 dB, while a rear-facing configuration with the Cardioid preset activated helps reduce unwanted bass radiation behind the system. Two XLR/TRS combo inputs, two XLR Thru outputs, and a dedicated subwoofer output provide flexible connectivity for external mixers and additional sound reinforcement equipment. Bluetooth 5.4 with AAC, SBC, and aptX codec support enables wireless audio playback from compatible devices.
Built for regular professional use, the MAUI 66 G3 features an 18 mm birch multiplex subwoofer enclosure finished with durable black polyurea coating and powder-coated aluminum columns. Four ergonomic handles on the subwoofer and recessed carrying handles in the column sections assist with transportation and positioning. The cable-free column connection and automatic detection simplify assembly without requiring separate speaker cables between the system components. Combining powerful bass, extended sound projection, controlled dispersion, and rugged construction, the MAUI 66 G3 is ideal for mobile DJs, live bands, outdoor festivals, corporate productions, and professional event service providers.
