Sound Barrier SBLA121 — 12″ Passive Two-Way Line Array Module
SBLA121 Overview
The Sound Barrier SBLA121 is a compact passive two-way line array module built to deliver high-power, high-bass-impact performance across concert, theater, and commercial event environments. Its scalable architecture makes it equally at home in live touring, corporate AV, and permanent installation contexts. The SBLA121 supports both flown and ground-stacked configurations via its integrated grid system, providing deployment flexibility across a wide range of venue types. It is well-suited for audio engineers, system integrators, and installation professionals who require a versatile, full-bandwidth line array solution.
Despite its compact enclosure footprint, the SBLA121 is engineered as a full-bandwidth system, capable of operating without subwoofers in many applications, reducing system complexity and rigging load where appropriate.
