In this article, we’ll take a closer look at JBL’s current line array lineup, highlighting their features, applications, and what makes each system stand out.

1. JBL VTX Series – The Flagship Touring Range

The VTX Series is JBL’s top-tier offering for professional touring and high-end installations. Built with cutting-edge transducer technology, advanced waveguides, and rugged touring hardware, the VTX line is designed for maximum SPL, consistent coverage, and road-ready reliability.

VTX A12 / A12W
A compact, dual 12-inch system delivering outstanding clarity and power. The A12 features JBL’s patented Radiation Boundary Integrator (RBI) for seamless high-frequency coverage and wide dispersion. The “W” version offers an extra-wide 120° horizontal pattern, perfect for arenas or venues where broad coverage is critical.

VTX A8
A versatile, dual 8-inch system offering full-range performance in a smaller footprint. Ideal for theatres, corporate events, and as a downfill in larger VTX rigs.

VTX B28 Subwoofer
A high-output dual 18-inch subwoofer delivering deep, controlled low-end reinforcement for the VTX arrays. Designed to integrate seamlessly with the A-series tops for a powerful, cohesive sound.

Best For: Large-scale touring, festivals, arenas, stadiums.

2. JBL SRX900 Series – High-Performance with Scalable Flexibility

The SRX900 Series brings JBL’s touring-grade technology into a more compact, scalable system that’s ideal for regional sound companies, mid-size venues, and houses of worship.

SRX906LA
A dual 6.5-inch powered line array element with built-in DSP and amplification. Compact but mighty, perfect for small-to-medium events or as a front-fill in larger systems.

SRX910LA
A dual 10-inch powered array module offering a bigger throw and wider frequency range, making it a flexible workhorse for many event types.

4. JBL CBT Series – Column Arrays for Installations

Provides even coverage over a wide area without the need for complex DSP or multiple loudspeakers.

Excellent for houses of worship, lecture theatres, retail spaces, and public address systems.
