The MAUI 66 G3 is a high-performance, fully active 4-way column PA system with a passive cardioid column design. As the flagship of the MAUI series, it combines powerful full-range sound, plenty of headroom, punchy deep bass and controlled dispersion with the fast, straightforward handling the MAUI series is known for.

The high-power 18" neodymium woofer is paired with a low-tuned bass-reflex enclosure to deliver powerful, precise low end down to 28 Hz. Elliptical, airflow-optimised bass reflex ports reduce turbulence and port noise, ensuring clean, defined bass even at high output levels.

The two-piece column houses a total of 16 × 3.5" neodymium midrange drivers and 4 × 1" compression drivers. In the upper column section, newly developed phase plugs and BEM-optimised waveguides ensure even, controlled dispersion. 

Two of the midrange drivers are positioned above the high-frequency section, giving the system its impressive reach and midrange clarity, even in open-air applications.

The lower column section features horn-loaded midrange drivers for increased efficiency, substantial headroom and powerful, clear vocal reproduction. The result is coherent mid- and high-frequency reproduction with a dispersion pattern of 120° × 25°.

The column's passive cardioid design directs sound energy towards the audience while attenuating rearward radiation by up to 18 dB. This significantly reduces unwanted sound on stage. With an additional rear-facing MAUI 66 G3 SUB and the Cardioid preset, this principle can be extended to the low-frequency range, increasing bass output towards the audience while noticeably reducing it behind the system. For maximum bass boost, the second subwoofer can instead be positioned facing forwards, doubling the sound pressure in the low-frequency range (+6 dB).

A Class-D amplifier delivers 1,900 W RMS (3,800 W peak), enabling a maximum SPL of 135 dB. The fully active 4-way architecture uses dedicated driver groups and amplifier channels for each frequency band. Crossover frequencies are set at 200 Hz, 700 Hz and 1,800 Hz. Equipped with DynX® DSP (Gen. 2) and advanced peak, RMS and thermal limiters, the MAUI 66 G3 delivers clean, undistorted sound even at the highest output levels.

Two XLR/TRS combo inputs, two Thru outputs and a dedicated sub output allow for straightforward system integration and flexible expansion. Bluetooth 5.4 with SBC and AAC codec support enables convenient wireless playback.

The polyurea-coated birch multiplex subwoofer enclosure and rugged aluminium columns are built to withstand everyday professional use. Four ergonomic carrying handles on the subwoofer and recessed handles in the columns make transport and handling easier.

The MAUI 66 G3 is ideal for DJs, bands and event service providers who value the streamlined handling of the MAUI series but want maximum bass and extended reach.
