LD Systems MAUI 66 G3 W

The LD Systems MAUI 66 G3 W is a professional, fully active 4-way column PA system featuring a powerful 18-inch subwoofer, a peak power output of 3,800 watts, and a maximum sound pressure level of 135 dB SPL. As the top model in the MAUI series, this system combines deep bass response down to 28 Hz with a wide dynamic range, controlled dispersion, and the rapid sound build-up for which MAUI systems are known. The white finish makes the MAUI 66 G3 W suitable for light-colored interiors, wedding venues, events, and permanent installations where the sound system needs to be as unobtrusive as possible.

The MAUI 66 G3 White is designed for professional DJs, live bands, events, and rental companies that require high sound pressure levels and a wide coverage area without the complexity of a traditional PA system. Thanks to its cardioid column design, sound is directed toward the audience while minimizing unwanted sound energy behind the speaker.

The system features an 18-inch neodymium subwoofer, sixteen 3.5-inch neodymium midrange drivers, and four 1-inch compression drivers. The redesigned speaker configuration, BEM-optimized waveguides, and second-generation DynX DSP technology ensure controlled sound reproduction across the entire frequency range.

Fully active 4-way system with 3,800 watts of peak power
The MAUI 66 G3 features a fully active 4-way speaker architecture in which separate amplifier channels and speaker groups handle the different frequency ranges. The built-in Class-D amplifier delivers 1,900 watts RMS and 3,800 watts peak power, with a maximum sound pressure level of 135 dB SPL. By processing the frequencies separately, each speaker group is driven within its optimal operating range. The crossover frequencies are set at 200 Hz, 700 Hz, and 1,800 Hz, ensuring that the subwoofer, the various midrange driver groups, and the compression drivers blend seamlessly. This configuration ensures a wide dynamic range and ample headroom, even at high sound levels. As a result, the MAUI 66 G3 is suitable for larger events, live performances, and other applications where powerful and consistent sound reproduction is essential.

18-inch neodymium subwoofer with bass response down to 28 Hz
The MAUI 66 G3 features a completely redesigned subwoofer with a powerful 18-inch neodymium woofer. It is housed in a low-tuned bass-reflex enclosure and delivers deep, controlled bass response extending down to 28 Hz. The combination of the larger woofer, an optimized magnet assembly, and the modified enclosure ensures higher sensitivity and a direct low-frequency response. As a result, both deep sub-bass frequencies and fast bass transients are reproduced accurately. The speaker chassis features a die-cast aluminum basket and is designed to handle high power levels without compromising control over the woofer. In addition, the subwoofer is equipped with specially shaped, elliptical bass-reflex ports. These are designed to improve airflow and minimize turbulence. This results in less port noise and keeps the bass response tight and defined, even when the system is used at higher volumes. For DJs and live bands that require a lot of low-frequency power, the 18-inch subwoofer offers the ability to combine deep bass with the advantages of a compact column PA system.

16 neodymium midrange drivers for a wide frequency range and clear sound reproduction
The MAUI 66 G3’s two-section speaker column contains a total of sixteen 3.5-inch neodymium midrange drivers.The configuration consists of eight horn-loaded drivers in the lower section of the column and eight drivers in the upper section. Two of these upper midrange drivers are positioned above the compression drivers. This specific design was developed to improve midrange reproduction over longer distances. Thanks to the additional midrange drivers above the high-frequency section, vocals and instruments remain clearly audible even at greater distances. This offers advantages for larger audience setups and outdoor events, where the sound must remain clear not only close to the stage but also further into the audience. The lower eight midrange drivers feature a horn design. This increases efficiency and provides more headroom. At the same time, the controlled directivity ensures better coherence of the sound waves and reduces unwanted reflections. This configuration contributes to a powerful, direct, and intelligible sound reproduction, particularly when reproducing vocals, guitars, keyboards, and other instruments in the midrange.

Four compression drivers with BEM-optimized waveguides
For high frequencies, the MAUI 66 G3 features four 1-inch compression drivers with specially developed waveguides. These waveguides are optimized using BEM (Boundary Element Method) technology. This ensures that the dispersion of the high frequencies is precisely tuned to the rest of the loudspeaker system. The waveguides work in conjunction with optimized phase plugs to distribute sound energy evenly across the listening area. The system has a horizontal coverage angle of 120° and a vertical coverage angle of 25°. This allows it to reach a wide audience while keeping vertical coverage limited. This helps reduce unwanted reflections off ceilings and other surfaces. At the same time, the high-frequency response remains clear and consistent across a large listening area. The combination of the compression drivers, BEM waveguides, and the additional midrange drivers above the high-frequency section ensures a coherent reproduction of the midrange and high-frequency ranges.

Cardioid column design with up to 18 dB rear attenuation
A key feature of the MAUI 66 G3 is the passive cardioid design of the loudspeaker column. Whereas conventional speakers disperse some of their sound energy toward the rear, the MAUI 66 G3 directs the sound primarily toward the audience. Within the frequency range of 100 Hz to 1 kHz, rear sound radiation is reduced by up to 18 dB. This offers significant advantages for live performances and events. Less sound reaches the stage, so musicians and sound engineers are less bothered by the PA system. It also reduces the risk of unwanted reflections and acoustic feedback. This is particularly beneficial when microphones are positioned close to the loudspeaker system. The controlled dispersion also ensures a more focused sound distribution toward the audience, without directing an unnecessary amount of sound energy toward the rear or surrounding surfaces. 

Expandable with a second subwoofer for extra bass power or cardioid operation
For applications requiring more low-frequency power, the MAUI 66 G3 can be expanded with a second MAUI 66 G3 subwoofer. When both subwoofers are pointed forward, the sound pressure in the low-frequency range can be increased by up to 6 dB. This provides additional bass power for larger events, DJ sets, and applications where powerful sub-bass reproduction is desired. Another option is a cardioid subwoofer configuration. In this setup, the second subwoofer is pointed backward, and the corresponding Cardioid DSP preset is used. With this configuration, the low-frequency output is directed forward, and bass radiation behind the system is reduced. This is particularly useful for live stages and events where powerful bass reproduction is desired for the audience, but where low-frequency output on stage must be minimized as much as possible. Thanks to its ability to extend the low-frequency range, the MAUI 66 G3 can be adapted to different venues, audience sizes, and applications.

DynX DSP Generation 2 with Advanced Protection
The MAUI 66 G3 is equipped with LD Systems’ second-generation DynX DSP technology. This digital signal processing monitors the performance of the loudspeaker system and optimizes sound reproduction at various sound levels. Advanced peak, RMS, and thermal limiters protect the amplifiers and speaker drivers from overload. This allows the system to utilize its full power without the sound quality being unnecessarily affected by distortion. The DSP technology also ensures precise coordination between the different speaker groups. As a result, the low-, mid-, and high-frequency sections work together as a single unit. Even when the system is used at high volumes, DynX DSP helps keep the sound reproduction controlled and balanced.

Bluetooth 5.4 with AAC and aptX for wireless audio playback
In addition to professional audio connections, the MAUI 66 G3 features Bluetooth 5.4 for wireless audio streaming. The system supports, among others, the AAC and aptX audio codecs, allowing music to be played from compatible smartphones, tablets, and other Bluetooth devices. Support for these codecs enables high-quality wireless audio playback, depending on the capabilities of the connected device. Bluetooth is ideal for background music, intermission music, and other situations where a wireless audio source needs to be connected quickly. As a result, the MAUI 66 G3 can not only be used as part of a professional PA system but can also play music on its own without additional playback devices with wired connections.

Professional Connectivity The MAUI 66 G3 features two combined XLR/6.35 mm jack inputs for connecting a mixing console, DJ controller, or other audio source. In addition, two XLR Thru outputs are available to route the incoming audio signal to other speakers or systems. A separate subwoofer output allows you to further expand the setup with additional bass reproduction. Thanks to these connection options, the MAUI 66 G3 can be integrated into a wide range of professional sound systems, from mobile DJ setups to larger live PA systems.

Quick setup without separate speaker cables
Despite its high power output and extensive speaker configuration, the MAUI 66 G3 retains the modular design of the MAUI series. The system consists of a subwoofer and a two-part speaker column that are stacked directly on top of each other. The integrated connectors provide the electrical connection between the various components, eliminating the need for external speaker cables between the subwoofer and the column. In addition, the system features automatic column detection. This allows the system to recognize the connected speaker configuration and be quickly set up for use. This design minimizes the amount of cabling and makes the MAUI 66 G3 suitable for mobile applications where the system is frequently set up and taken down.

Robust Construction for Professional Use
The subwoofer enclosure of the MAUI 66 G3 is made of birch plywood and features a protective polyurea coating. This finish protects the enclosure from the stresses caused by transport, setup, and daily use. The speaker columns are made of aluminum and feature a powder-coated finish. This combines a sturdy construction with a precise fit between the various column sections. The subwoofer is equipped with four ergonomically placed handles for moving the system. The column sections also feature recessed handles, making it easier to lift and transport the components. With a total weight of approximately 57.1 kg, the MAUI 66 G3 is designed for professional use where sound power, portability, and quick setup are essential. The white finish makes the MAUI 66 G3 W suitable for light-colored interiors, wedding venues, events, and permanent installations where the sound system should be as unobtrusive as possible.
