LD Systems LDM44G3SUBUS  (LD Systems Maui 44 G3 Sub)

Powered Extension Subwoofer

The LD Systems MAUI 44 G3 SUB is a high-performance 15-inch powered extension subwoofer designed to enhance the low-frequency output of the MAUI 44 G3 column PA system. Featuring a powerful neodymium woofer, deep bass extension down to 34 Hz, and DynX Gen. 2 DSP technology, it provides additional bass reinforcement for DJs, live performances, and professional sound applications. Its dedicated cardioid preset allows users to configure controlled low-frequency coverage, while its rugged birch plywood enclosure and automatic FOLLOWER mode make integration and setup straightforward.

LD Systems MAUI 44 G3 SUB Competitive Differences

• Dedicated 15-inch powered extension subwoofer designed specifically for expanding the low-frequency performance of the MAUI 44 G3 column PA system.
• High-power neodymium woofer with a 4-inch voice coil and bass extension down to 34 Hz for deep, defined low-frequency reproduction.
• Supports forward-facing bass expansion or rear-facing cardioid configurations to increase audience-facing bass while reducing unwanted low-frequency radiation behind the system.
• DynX DSP Generation 2 with advanced limiting and thermal protection helps maintain consistent, controlled bass performance.
• Automatic FOLLOWER mode activates when no column is connected, simplifying integration with an existing MAUI 44 G3 system.
• Airflow-optimized bass-reflex enclosure reduces port turbulence and unwanted noise during high-output operation.
• Durable 18 mm birch multiplex cabinet with polyurea coating, protective steel grille, and four ergonomic handles for professional transport and handling.

LD Systems MAUI 44 G3 SUB Description

The LD Systems MAUI 44 G3 SUB provides additional low-frequency reinforcement for MAUI 44 G3 column PA systems. Its custom 15-inch neodymium woofer features a 4-inch voice coil and an optimized bass-reflex design that produces powerful, controlled bass while minimizing port noise and turbulence. DynX Gen. 2 digital signal processing incorporates advanced limiting and protection functions to maintain dependable operation during demanding performances. The subwoofer is designed for mobile DJs, live bands, event production companies, and professional sound reinforcement installations requiring greater low-frequency output.

The MAUI 44 G3 SUB offers two practical expansion configurations. For increased bass output, the additional subwoofer can be positioned facing forward alongside the main MAUI 44 G3 system with the cardioid preset disabled, providing up to 6 dB more low-frequency sound pressure in the appropriate configuration. For improved bass directivity, positioning the extension subwoofer facing backward and activating its dedicated Cardioid preset reduces unwanted rearward bass radiation while reinforcing low frequencies toward the audience. This flexibility helps optimize sound performance for different venues, stage arrangements, and audience areas.

System integration is straightforward thanks to the automatic FOLLOWER mode, which activates when no column is installed. The extension subwoofer connects to the Sub-Out or System-Out of a compatible MAUI 44 G3 system using an XLR cable connected to the right input of the follower unit. Its rugged 18 mm birch multiplex enclosure features a protective polyurea coating and shock-resistant steel front grille for demanding professional use. Four ergonomic carrying handles simplify transport and positioning, while its compact enclosure maintains the same footprint as the MAUI 44 G3 system subwoofer.
