L-Acoustics SB28

The L-Acoustics SB28 is a high-performance subwoofer designed to deliver deep, powerful bass in a variety of professional audio applications. Known for its exceptional sound quality, the SB28 is frequently used in large-scale live sound environments, including concerts, festivals, and other events where high SPL (Sound Pressure Level) and extended low-frequency response are required. It is a key component of the L-Acoustics line of sound reinforcement systems, offering both versatility and robustness.

At the heart of the SB28 are its two 18-inch direct-radiating drivers, which are capable of producing frequencies as low as 25 Hz. These drivers are mounted in a bass-reflex enclosure that is carefully tuned to optimize performance, minimize distortion, and ensure a smooth, extended low-frequency output. The cabinet is constructed from high-quality birch plywood, which provides durability while maintaining a relatively lightweight design. The front of the subwoofer is covered with a protective steel grill, and the overall build quality is designed to withstand the rigors of touring and high-demand applications.

The SB28 subwoofer is designed to be highly efficient and easy to deploy in various configurations. It features integrated rigging hardware, allowing for quick and secure array configurations, whether used in a standalone mode or as part of a larger L-Acoustics system. The subwoofer is often paired with other L-Acoustics products, such as the K1 or V-DOSC line arrays, to create a full-range audio system capable of delivering exceptional sound across the entire frequency spectrum. Additionally, the SB28 can be operated in both cardioid and omnidirectional modes, providing sound engineers with the flexibility to tailor the bass response to the specific needs of the venue.

In terms of connectivity and control, the SB28 is typically powered and controlled by L-Acoustics amplified controllers like the LA12X or LA8. These controllers are pre-configured with specific presets for the SB28, ensuring optimal performance and protection of the drivers. The integration with L-Acoustics amplified controllers also allows for advanced signal processing and remote monitoring, making it easier for sound engineers to manage and fine-tune the system in real-time. This seamless integration is one of the hallmarks of the L-Acoustics ecosystem, ensuring that all components work together to deliver consistent and high-quality audio.
