(LD Systems MAUI 44 G3)
Powered Cardioid Column PA System
The LD Systems MAUI 44 G3 is a high-performance 4-way powered column PA system designed for DJs, live bands, and professional event sound reinforcement. Delivering 3600W peak power and a maximum output of 133 dB SPL, it combines a powerful 15-inch neodymium subwoofer with 14 midrange drivers and four high-frequency compression drivers. Its passive cardioid column design reduces unwanted rearward sound, while DynX Gen. 2 DSP, Bluetooth 5.4 connectivity, and cable-free column assembly provide powerful performance with convenient setup and operation.

LD Systems MAUI 44 G3 Description
The LD Systems MAUI 44 G3 combines powerful amplification with a fully active four-way architecture to deliver detailed sound across a wide frequency range. Its high-performance 15-inch neodymium woofer features a 4-inch voice coil and an airflow-optimized bass-reflex enclosure that minimizes port turbulence while producing defined bass. The two-piece column houses 14 custom 3.5-inch neodymium midrange drivers and four 1-inch neodymium compression drivers. Horn-loaded midrange sections, BEM-optimized waveguides, and phase plugs work together to improve efficiency, vocal clarity, and consistent sound distribution throughout the coverage area.
The system's passive cardioid column design reduces rearward radiation by up to 18 dB across the 100 Hz to 1 kHz frequency range, helping minimize unwanted stage sound and improve directional control. Its 120° horizontal by 25° vertical dispersion provides broad audience coverage while limiting unnecessary vertical spread. The integrated Class-D amplification delivers 1800W RMS and 3600W peak power, while DynX Gen. 2 DSP manages signal processing through advanced peak, RMS, and thermal limiters. Dedicated amplifier channels and crossover points at 200 Hz, 700 Hz, and 1800 Hz help maintain balanced reproduction throughout the system's operating range.
For larger events or applications requiring additional bass performance, the MAUI 44 G3 can be expanded with an optional MAUI 44 G3 SUB. Positioning a second subwoofer forward can increase low-frequency output by up to 6 dB, while a rear-facing configuration with the Cardioid preset helps reduce bass energy behind the system. Two XLR/TRS combo inputs, two XLR Thru outputs, and a dedicated subwoofer output allow flexible integration with external mixers and additional sound reinforcement equipment. Bluetooth 5.4 provides wireless audio streaming from compatible devices, making the system practical for music playback and live event applications.
Built for regular transport and professional use, the MAUI 44 G3 features an 18 mm birch multiplex subwoofer enclosure with a protective polyurea coating and a powder-coated aluminum column assembly. Four ergonomic subwoofer handles and recessed column handles make loading and handling more convenient. The cable-free column connection and automatic detection simplify setup without requiring separate speaker cables between the column sections and subwoofer. With its rugged construction, high output, and controlled dispersion, the MAUI 44 G3 is suited for mobile DJs, live bands, corporate productions, and professional event providers.
