L-Acoustics SB18

The L-Acoustics SB18 is a versatile, compact subwoofer designed to deliver powerful low-frequency extension for a wide range of sound reinforcement applications. Engineered to provide exceptional bass performance, the SB18 is a preferred choice for venues that require high-impact sound, such as concert halls, theaters, nightclubs, and outdoor events. Its compact size makes it easy to integrate into various sound system configurations, making it a highly adaptable solution for both permanent installations and mobile setups.

At the heart of the L-Acoustics SB18 is an 18-inch, front-loaded driver that has been specifically designed to deliver deep, punchy bass with clarity and precision. This high-efficiency driver is capable of handling significant power, ensuring that the SB18 can deliver a maximum SPL of 138 dB, which is more than adequate for creating an impactful low-frequency experience in a variety of settings. The SB18’s design allows it to produce a frequency response that extends down to 32 Hz, providing the kind of deep, resonant bass that is essential for genres of music that rely on powerful low-end content, such as electronic dance music, hip-hop, and rock.

One of the key features of the SB18 is its compatibility with the L-Acoustics modular sound systems, particularly the ARCS, KARA, and coaxial systems. The SB18 is designed to seamlessly integrate with these systems, providing a consistent and coherent sound signature across the full frequency range. This integration is facilitated by the use of L-Acoustics’ proprietary amplified controllers, such as the LA4X and LA8, which provide precise control over crossover points, equalization, and delay settings, ensuring that the SB18’s performance is perfectly aligned with the other elements of the sound system. Additionally, the SB18 can be used in both standard and cardioid configurations, allowing sound engineers to tailor the bass response to suit the acoustics of the venue and the specific requirements of the performance.

The SB18 is also designed with practical considerations in mind. Its compact, rugged enclosure is constructed from high-quality Baltic birch plywood, making it durable and capable of withstanding the rigors of touring and live performance. The enclosure is coated with a hard-wearing, weather-resistant finish, ensuring that the SB18 can be used in a wide range of environments, including outdoor settings. The SB18 features ergonomic handles and integrated rigging hardware, making it easy to transport, set up, and integrate into flown or ground-stacked configurations. These design features make the SB18 a highly practical and versatile choice for both touring professionals and installation companies.
