LD Systems Maui 66 G3 Sub W

Powered Extension Subwoofer

The LD Systems MAUI 66 G3 SUB W is a high-performance 18-inch powered extension subwoofer designed to enhance the low-frequency output of the MAUI 66 G3 W column PA system. Featuring a powerful neodymium woofer, deep bass extension down to 28 Hz (-10 dB), and DynX Gen. 2 digital signal processing, it delivers controlled bass reinforcement for DJs, live performances, and professional sound applications. Its dedicated cardioid preset provides flexible low-frequency directionality, while the rugged white birch plywood enclosure and automatic FOLLOWER mode simplify integration with an existing MAUI 66 G3 W system.

LD Systems MAUI 66 G3 SUB W Description

The LD Systems MAUI 66 G3 SUB W provides additional low-frequency reinforcement for the MAUI 66 G3 W column PA system. Its custom 18-inch neodymium woofer features a 4-inch voice coil and a low-tuned bass-reflex enclosure engineered to produce deep, precise bass while minimizing unwanted port noise. Airflow-optimized bass-reflex ports help reduce turbulence at high output levels, while DynX Gen. 2 digital signal processing manages low-frequency reproduction and system protection. This extension subwoofer is designed for mobile DJs, live bands, event production companies, and professional sound reinforcement applications requiring additional bass output.

The MAUI 66 G3 SUB W offers two flexible configurations for different performance environments. For increased bass output, the extension subwoofer can be positioned facing forward alongside the main MAUI 66 G3 W system with the cardioid preset disabled. This arrangement can increase low-frequency output by up to 6 dB in the compatible system configuration. For greater bass directionality, the additional subwoofer can be positioned facing backward with its dedicated Cardioid preset activated. Working together with the main system's subwoofer, this configuration reduces unwanted rearward bass radiation while reinforcing low frequencies toward the audience, making it useful for live stages and acoustically challenging venues.

System integration is straightforward thanks to automatic FOLLOWER mode, which activates when no speaker column is installed. The extension subwoofer connects to the Sub-Out of the MAUI 66 G3 W system using an XLR cable connected to the right input of the follower subwoofer. Its integrated signal processing and 200 Hz crossover support coordinated low-frequency operation with the main system. This allows users to expand their existing sound reinforcement setup without replacing the original column PA system.

Built for dependable professional use, the MAUI 66 G3 SUB W features a rugged 18 mm birch multiplex enclosure finished with a durable white polyurea coating. Its protective steel front grille helps shield the woofer from damage, while four ergonomic carrying handles make transportation, loading, and positioning more convenient. The enclosure matches the dimensions and white finish of the MAUI 66 G3 W system subwoofer, providing a consistent setup for wedding entertainment, corporate productions, live performances, houses of worship, and professional event installations.
