LD Systems Stinger SUB 18 A G3 Active 800W 18Inch Bass Reflex PA Subwoofer (LDESUB18AG3)

The LD Systems Stinger SUB 18 A G3 is a high-performance active 18” bass reflex PA subwoofer designed to deliver deep, powerful, and controlled low-frequency reinforcement for professional sound systems. Built for demanding live sound, touring, and installation applications, it combines high output, advanced DSP processing, and rugged construction to meet the needs of modern audio professionals.

At the core of the Stinger SUB 18 A G3 is a high-efficiency 800 watts RMS digital power amplifier, capable of delivering an impressive maximum sound pressure level of 135 dB. This powerful amplification system ensures strong, impactful bass reproduction even in large venues and high-energy environments. Whether used for live concerts, DJ setups, festivals, or permanent installations, the subwoofer provides the necessary low-end foundation for a full-range PA system.

The subwoofer features a specially designed 18-inch custom woofer, engineered to deliver extended low-frequency performance down to 35 Hz. This allows the system to reproduce deep, punchy bass with excellent clarity and definition. From tight kick drums to powerful electronic basslines, the Stinger SUB 18 A G3 ensures that low-end audio is felt as much as it is heard, enhancing the overall impact of any sound system.

Advanced DynX® DSP technology is integrated into the system to guarantee distortion-free performance even at high output levels. This intelligent digital signal processing manages dynamics, protects components, and optimises sound quality, ensuring consistent and clean bass reproduction under all operating conditions. As a result, users can rely on stable performance even when the system is pushed to its limits.

For flexible system integration, the subwoofer offers selectable low-pass filter presets at 80 Hz, 100 Hz, and 120 Hz. These presets allow users to easily match the subwoofer with different full-range speakers and system configurations, ensuring smooth crossover alignment and optimal frequency distribution. This makes system setup faster and more efficient while maintaining professional sound quality.

The Stinger SUB 18 A G3 also includes cardioid subwoofer array presets, enabling users to control low-frequency dispersion and reduce unwanted bass radiation on stage. This feature is particularly valuable in live performance environments, where minimising stage noise and improving front-of-house clarity are essential. By directing bass energy more effectively, cardioid configurations help create a cleaner and more controlled sound environment.

Designed for flexible deployment, the subwoofer can be used in both horizontal and vertical orientations, allowing it to adapt to different stage layouts and venue requirements. This versatility makes it suitable for a wide range of applications, from compact mobile setups to large-scale installed systems.

The enclosure is constructed from durable 18 mm birch plywood, known for its strength, acoustic performance, and reliability. This robust cabinet design is finished with an ultra-rugged polyurea coating, providing exceptional resistance to scratches, impacts, and wear from frequent transport and handling. The durable finish ensures long-term protection, making the subwoofer ideal for touring and rental applications.

For ease of use and transport, the Stinger SUB 18 A G3 is equipped with ergonomic carrying handles and integrated stacking recesses. These features make it easier to lift, position, and stack the subwoofer safely during setup and breakdown. The thoughtful design improves workflow efficiency for audio technicians and event crews working in fast-paced environments.

A shock-resistant front grille provides maximum protection for the 18-inch woofer, safeguarding it against physical damage during transport and operation. This heavy-duty grille ensures that the internal components remain secure and protected while maintaining optimal acoustic performance.

The subwoofer also includes an M20 threaded pole mount insert, allowing secure attachment of satellite speakers via distance rods. This enables the creation of compact, full-range PA systems with stable and professional speaker positioning.

To further support mobility and professional use, the Stinger SUB 18 A G3 is compatible with a range of smart transport accessories, making handling and system deployment even more efficient. These accessories help simplify logistics and improve convenience for touring professionals and rental companies.
