Product Details

High-Power Performance

The L-Acoustics SB18 is a compact subwoofer designed to extend the bandwidth of the KARA II system for mobile and touring applications. It also features a high-excursion, direct-radiating 18″ transducer in a dual bass-reflex tuned enclosure. Thus, the design ensures powerful and deep bass performance.

Versatile and Durable Design

Deploy the SB18 in standard or cardioid configurations with dedicated presets. It mechanically and acoustically couples with KARA II to reinforce, contour, and therefore extend the bandwidth down to 32 Hz. The subwoofer features L-Vents, which significantly reduce turbulence and port noise at high levels, enhancing low-frequency efficiency.

Constructed from premium grade Baltic beech and birch plywood, the SB18 also ensures maximum acoustical and mechanical integrity. Its four-point, captive rigging system simplifies deployment and provides a visual safety assessment. Additionally, the L-Acoustics SB18 is weatherized to achieve an IP55 rating for reliable outdoor operations.
