Sound Barrier SBLA8 — Compact Three-Way Bi-Amp Line Array Module
SBLA8 Overview
The Sound Barrier SBLA8 is a compact, passive three-way bi-amp line array enclosure engineered to deliver true line array performance in small to medium-scale applications. The system integrates constant directivity horn design with horn loading techniques to maximize dynamic impact in a flyable, ground-stackable form factor. Rated full-range at -3dB at 80Hz, the SBLA8 is capable of operating without subwoofers in many applications, and pairs directly with the Sound Barrier SBLA18SUB when additional low-frequency extension is required. It is well-suited for audio engineers and system integrators deploying scalable arrays in corporate event spaces, theatres, indoor venues, and large-scale outdoor reinforcement delay positions.
The SBLA8’s modular design supports both flown and ground-stacked configurations, providing deployment flexibility across a wide range of production environments without compromising system coherence or coverage consistency.
Key Features
