The L‑Acoustics SB18 is a compact, high‑performance 18‑inch subwoofer engineered to extend system bandwidth with tight, musical low‑frequency reproduction. A neodymium 18‑inch transducer sits in a dual bass‑reflex enclosure with a progressive‑profile vent to maintain laminar airflow at high SPLs, reducing turbulence and distortion. With 700 W RMS power handling, up to 138 dB maximum SPL (preset dependent) and an 8 Ω nominal impedance, the SB18 offers impressive headroom, efficiency and system flexibility. Built from rugged Baltic birch plywood, it integrates seamlessly with L‑Acoustics WST line sources and coaxial enclosures and can be deployed singly, in arrays, or in cardioid configurations for precise pattern control and cleaner stages. This package includes a protective cover and a removable front dolly with wheels to speed load‑ins and protect the cabinet between shows. Choose the SB18 to add controlled, impactful sub‑bass that enhances clarity and punch for live music, theatre, corporate events and fixed installations.
