LD Systems MAUI 66 G3 W – high-performance column PA system for professional applications

With the MAUI 66 G3 W, LD Systems offers the most powerful model in the MAUI series. This fully active 4-way column PA system was developed for professional DJs, bands, and event service providers seeking a powerful sound system with exceptionally deep bass response and long-range coverage.

The design combines a powerful full-range sound with controlled sound dispersion and the quick setup for which the MAUI series is known. The speaker components are finely tuned to work together, forming an active system that reproduces the various frequency ranges via dedicated driver groups and amplifier channels.

In its white version, the LD Systems MAUI 66 G3 Active All-in-One Array Column PA System offers an alternative to the classic black speaker design. The combination of a white subwoofer and matching aluminum columns is particularly well-suited for users who value not only sound performance but also the visual integration of the equipment.

18-inch neodymium subwoofer with deep bass down to 28 Hz

At the heart of the MAUI 66 G3 W is a powerful 18-inch neodymium woofer with a 4-inch voice coil. It operates within a low-tuned bass-reflex enclosure and delivers powerful reproduction of low frequencies. The specified frequency range of the entire system extends down to 28 Hz at -10 dB.

Special attention was paid to the design of the bass reflex ports. Elliptical, aerodynamically optimized ports reduce air turbulence and the associated flow noise. As a result, bass reproduction remains defined and precise even at high volume levels.

The subwoofer is housed in an enclosure made of 18 mm thick birch multiplex and features a durable polyurea coating. A steel front grille complements the robust construction. Four ergonomic carrying handles make it easy to handle the 43.68 kg subwoofer.

16 neodymium midrange drivers for powerful and clear sound reproduction

The MAUI 66 G3 W’s two-piece speaker column houses a total of 16 midrange drivers, each with a diameter of 3.5 inches. The drivers feature neodymium magnets and 1-inch voice coils. They handle the reproduction of the midrange frequencies and contribute significantly to the system’s speech intelligibility and musical impact.

The two column elements employ different design features for targeted sound dispersion. The lower column element uses horn-loaded midrange drivers. This design increases efficiency and supports powerful, clear sound reproduction, particularly in the vocal range.

The upper column element also features two midrange drivers positioned above the tweeters. Their placement ensures a well-defined midrange reproduction even at greater distances. The speaker arrangement has thus been specifically tailored to the requirements of high-performance sound reinforcement.

Four compression drivers with BEM-optimized waveguides

For high-frequency reproduction, the LD Systems MAUI 66 G3 Active All-in-One Array White column PA system features four 1-inch compression drivers. These are equipped with waveguides that enable precise and controlled sound dispersion.

The upper column element incorporates newly developed phase plugs and BEM-optimized waveguides. They have been tuned for homogeneous dispersion and contribute to uniform reproduction of midrange and high frequencies.

Together with the horn-loaded midrange drivers, this results in a coherent sound wavefront. The horizontal dispersion angle is 120 degrees, while the vertical dispersion is designed for 25 degrees. This allows the system to direct sound precisely toward the intended audience area.

Passive cardioid design for controlled sound dispersion

A distinctive feature of the MAUI 66 G3 W is the passive cardioid design of the speaker column. This design focuses the sound energy primarily toward the audience while simultaneously reducing rear sound radiation.

In the frequency range from 100 Hz to 1 kHz, the cardioid column achieves a reduction in rear sound radiation of up to 18 dB. As a result, less unwanted sound reaches the area behind the loudspeaker system.

This targeted sound dispersion can be a significant advantage, particularly at events with a stage. While the audience directly in front of the system is addressed, rear sound energy in the corresponding frequency range is significantly reduced.

The cardioid characteristics are achieved through the optimized speaker design. Together with the waveguides, phase plugs, and the arrangement of the midrange drivers, this creates a complete system designed for controlled sound distribution.

Expandable with a second MAUI 66 G3 subwoofer

For applications with particularly high demands on bass reproduction, the MAUI 66 G3 W can be expanded with a second MAUI 66 G3 SUB. Two different setup options are available.

Additional bass impact from a second subwoofer

If the additional subwoofer is facing forward, it serves to boost bass reproduction. According to the manufacturer, this configuration enables a 6 dB increase in sound pressure in the bass range. This allows the system to be expanded for applications with particularly high demands on low-frequency levels.

Cardioid subwoofer setup for reduced rear radiation

Alternatively, the second subwoofer can be oriented toward the rear. In combination with the designated cardioid preset, this creates directional bass radiation. This directs the sound energy in the bass range primarily toward the audience and reduces it behind the system.

This expansion option complements the column’s existing passive cardioid design and enables precise control of bass reproduction.

Class-D amplifier with 3,800 watts of peak power

The MAUI 66 G3 W is powered by an integrated Class-D amplifier. It delivers an RMS output power of 1,900 watts and a peak power of 3,800 watts. The maximum sound pressure level is 135 dB SPL.

The fully active 4-way architecture uses separate driver groups and amplifier channels for the different frequency ranges. The crossover frequencies are 200 Hz, 700 Hz, and 1,800 Hz. This ensures that the individual speaker components are utilized according to their intended functions.

The system’s frequency response ranges from 33 Hz to 20,000 Hz at -6 dB and from 28 Hz to 20,000 Hz at -10 dB. These technical specifications highlight the combination of deep bass reproduction and a wide frequency response.

Second-Generation DynX DSP for Controlled Performance

For internal signal processing, LD Systems relies on second-generation DynX DSP. The digital signal processing supports playback at high volume levels and incorporates advanced protection and limiter functions.

These include peak, RMS, and thermal limiters. They serve to protect the speaker components and amplifier electronics within the specified operating limits and enable controlled playback even at high levels.

The AD/DA converters operate at a sampling rate of 48 kHz. The specified bit depths are 32-bit and 24-bit. The minimum signal-to-noise ratio is 106 dB.

Connectivity Options and Bluetooth 5.4

For integration into existing sound reinforcement systems, the MAUI 66 G3 W offers two XLR/jack combo inputs. In addition, two thru outputs and a separate subwoofer output are available. In total, the system thus has three outputs with three-pin XLR connectors.

These connections allow for the integration of external audio sources and the expansion of the speaker configuration. The dedicated subwoofer output is specifically designed for setups requiring additional bass support.

Bluetooth 5.4 is built-in for wireless audio transmission. Supported audio codecs include SBC, AAC, and aptX. This allows compatible audio sources to connect to the system via Bluetooth.

This model does not feature a built-in mixer. The MAUI 66 G3 W is designed as a high-performance active speaker system with the corresponding audio connections.

Quick setup with automatic column detection

The LD Systems MAUI 66 G3 Active All-in-One Array Column PA System in white combines its extensive speaker technology with a straightforward setup concept. The column elements can be connected without separate cables between the column components. Automatic column detection further simplifies setup.

The speaker column consists of two elements with an aluminum housing and a powder-coated finish. The entire column unit measures 103 mm wide, 1,813 mm high, and 136 mm deep. It weighs 13.43 kg.

The subwoofer features four ergonomic carrying handles. Additional handles on the column elements make it easier to carry and position the components.
