Key Specifications of JBL Concert Line Array Speakers

Power Handling

Power handling defines the maximum electrical power a speaker can safely manage without sustaining thermal or mechanical damage. Measured in watts (W), this specification is critical for matching amplifiers to speakers and avoiding distortion or component failure.

JBL line arrays typically feature high power handling—often ranging from 800W to over 2000W per cabinet—enabling them to deliver high sound pressure levels (SPL) required in large-scale live events. Continuous (RMS) and peak power ratings should both be considered when designing a sound system to ensure headroom and prevent clipping.

Drivers and Their Roles

JBL line arrays utilize a combination of specialized drivers to reproduce the full audio spectrum with precision. These include:

• Woofers: Handle low-frequency reproduction (bass), typically using large-diaphragm neodymium or ferrite magnet systems for deep, punchy bass response.
• Compression Drivers: Used with horn-loaded waveguides to efficiently project mid to high frequencies over long distances with minimal loss.
• Transducers: General term for components that convert electrical signals into mechanical motion (sound). In practice, this includes both woofers and compression drivers.

The quality, alignment, and integration of these drivers directly impact clarity, dispersion, and overall sonic fidelity.

Sensitivity

Sensitivity measures how efficiently a speaker converts power into sound, expressed in decibels (dB) at 1 watt of input measured from 1 meter away (dB @ 1W/1m). Higher sensitivity means greater output with less amplifier power.

JBL concert line arrays typically have sensitivity ratings between 98 dB and 110 dB, making them highly efficient for large venues. This efficiency reduces the need for excessive amplification, minimizing distortion and heat buildup, especially during extended performances.

Coverage Pattern

Coverage refers to the directional spread of sound emitted by the speaker. JBL line arrays are designed with controlled vertical and horizontal dispersion to ensure even sound distribution across audiences.

Vertical line arrays use closely spaced drivers to create a coherent wavefront, focusing sound over long distances with minimal front-to-back spill. Horizontal coverage is typically narrower (e.g., 90°–120°) to control side-to-side dispersion and reduce reflections. Advanced models offer adjustable curvature or digital beam steering for precise audience targeting.

Materials and Build Quality

JBL concert line arrays are built for durability under rigorous touring conditions. Enclosures are constructed from multi-ply Baltic birch plywood or reinforced composite materials, offering excellent strength-to-weight ratios and resistance to impact and moisture.

Grilles are made from powder-coated steel to protect drivers, while internal bracing enhances structural rigidity and reduces unwanted resonance. Rigging hardware—including flying points, brackets, and inter-cabinet connectors—is forged from high-strength steel or aluminum alloys to ensure safe suspension and alignment during installation.
