MAUI 66 G3 Cardioid Column PA System

Description

LD Systems MAUI 66 G3 Powered Column PA System – Massive Output, Deep Bass, and Precision Sound Coverage

Experience powerful, full-range sound with the LD Systems MAUI 66 G3 Powered Column PA System. As the flagship of the MAUI series, this fully active 4-way column speaker system delivers an impressive 3,800 watts of peak power, 135 dB maximum SPL, and deep bass extension down to 28 Hz. Designed for professional DJs, live bands, and event production companies, the MAUI 66 G3 combines the output and headroom of a high-performance PA with the streamlined setup and portability of a column array system. Its passive cardioid column design provides controlled audience coverage while reducing unwanted sound behind the system, making it an excellent solution for demanding live sound applications.

3,800 Watts of Powerful, Full-Range Sound

The MAUI 66 G3 delivers the power and clarity needed for larger performances and professional events. A high-efficiency Class-D amplifier produces 1,900 watts RMS and 3,800 watts peak, driving a fully active 4-way system with dedicated amplifier channels for each frequency band. With a maximum SPL of 135 dB, the system offers substantial headroom for dynamic music, powerful vocals, and high-energy performances.

3,800W peak / 1,900W RMS: High-output Class-D amplification for demanding applications.
135 dB maximum SPL: Powerful sound reinforcement with substantial headroom.
Fully active 4-way architecture: Dedicated driver groups and amplifier channels for optimized performance.
28 Hz–20 kHz frequency response: Extended low-frequency performance and detailed full-range reproduction.
DynX DSP Gen. 2: Advanced signal processing with peak, RMS, and thermal protection.

18-Inch Neodymium Subwoofer for Deep, Punchy Bass

At the foundation of the MAUI 66 G3 is a powerful 18-inch neodymium woofer housed in a low-tuned bass-reflex enclosure. Engineered to reproduce frequencies as low as 28 Hz, the system delivers the deep, controlled bass needed for electronic music, live drums, and high-energy events. Elliptical, airflow-optimized bass-reflex ports minimize turbulence and port noise, helping maintain clean, defined low frequencies even at high output levels.

18-inch neodymium woofer: Powerful low-frequency reproduction with high efficiency.
Bass extension down to 28 Hz: Deep low end for music and live sound reinforcement.
Low-tuned bass-reflex enclosure: Optimized for strong, controlled bass response.
Elliptical bass-reflex ports: Reduce airflow turbulence and unwanted port noise.

Advanced Column Array for Exceptional Clarity and Reach

The MAUI 66 G3 features a two-piece column array containing 16 neodymium 3.5-inch midrange drivers and four 1-inch compression drivers. The upper column incorporates newly developed phase plugs and BEM-optimized waveguides to deliver smooth, controlled high-frequency dispersion. Two midrange drivers positioned above the high-frequency section help extend projection and preserve midrange clarity over longer distances, including outdoor applications.

The lower column uses horn-loaded midrange drivers to increase efficiency and headroom, delivering powerful, articulate vocals and detailed instrument reproduction. Together, these technologies create a coherent sound field with a controlled 120° horizontal x 25° vertical dispersion pattern.

16 x 3.5-inch neodymium midrange drivers: Detailed midrange reproduction with strong projection.
4 x 1-inch compression drivers: Clear, controlled high-frequency output.
BEM-optimized waveguides: Even dispersion throughout the listening area.
Horn-loaded lower midrange section: Increased efficiency and powerful vocal reproduction.
120° x 25° coverage: Wide horizontal dispersion with controlled vertical coverage.

Passive Cardioid Column Design Reduces Stage Noise

Keep more sound directed toward the audience and less sound spilling onto the stage. The MAUI 66 G3 features a passive cardioid column design that reduces rearward sound radiation by up to 18 dB. This controlled dispersion helps minimize unwanted stage reflections and improves the listening environment for performers, particularly in acoustically challenging venues.

Up to 18 dB rear attenuation: Reduced sound radiation behind the column.
Controlled audience coverage: Focuses more sound energy toward listeners.
Reduced stage spill: Helps improve clarity and minimize unwanted reflections.
Cardioid performance: Specified rear attenuation across 100 Hz–1 kHz.

Expandable Bass with Cardioid and Forward-Facing Subwoofer Configurations

For productions that demand even greater low-frequency performance, the MAUI 66 G3 offers flexible subwoofer expansion. Add a second MAUI 66 G3 SUB behind the main system and select the Cardioid preset to direct more bass toward the audience while reducing low-frequency energy behind the system. Alternatively, position the additional subwoofer facing forward for a +6 dB increase in low-frequency sound pressure.

Cardioid subwoofer configuration: Improve front-to-back low-frequency control with an additional rear-facing subwoofer.
Forward-facing subwoofer configuration: Increase low-frequency SPL by up to 6 dB.
Dedicated subwoofer output: Simplifies system expansion.
Flexible deployment: Adapt bass performance to different venues and event requirements.

DynX DSP Gen. 2 for Consistent Performance

LD Systems' DynX DSP Gen. 2 helps maintain clarity and system protection at demanding output levels. Advanced peak, RMS, and thermal limiters manage the system's performance, while precisely configured crossover points at 200 Hz, 700 Hz, and 1,800 Hz ensure the individual driver groups work together efficiently.

DynX DSP Gen. 2: Advanced digital signal processing.
Peak, RMS, and thermal limiters: Help protect the system during demanding operation.
Optimized crossover frequencies: 200 Hz, 700 Hz, and 1,800 Hz.
Four-way active processing: Dedicated control across the frequency bands.

Flexible Connectivity and Bluetooth 5.4 Streaming

Connect professional audio sources quickly with two XLR/TRS combo inputs and two Thru outputs. A dedicated subwoofer output supports expanded low-frequency configurations, while integrated Bluetooth 5.4 provides convenient wireless audio playback from compatible devices.

2 XLR/TRS combo inputs: Connect mixers and compatible audio sources.

Road-Ready Construction with Streamlined Setup

Despite its impressive output capabilities, the MAUI 66 G3 retains the straightforward setup and handling that make the MAUI series popular with mobile professionals. The rugged subwoofer enclosure is constructed from birch plywood with a durable polyurea coating, while the two-piece aluminum column is built for regular professional use. Four ergonomic carrying handles on the subwoofer and recessed handles in the column sections make loading, transportation, and positioning more manageable.
