JBL CBT 50LA-1 50cm Tall Line Array Column Speaker, Black

The JBL CBT 50LA-1 is a compact line array speaker built for reliable, even coverage across medium-sized venues and live sound installations. Its slender 50cm profile delivers controlled directional performance, making it a dependable choice for speech reinforcement, background music, and distributed audio systems where tight mounting and clean sightlines matter for touring and permanent rigs alike.

Design & Build Quality

Built from fiberglass-reinforced ABS with UV-resistant paint, this speaker weighs just 4.1 kg (9.0 lb) and measures 528 × 99 × 153 mm, allowing easy rigging in tight spaces or above-ceiling installations without adding weight to your road load. The included swivel/tilt wall bracket offers continuously variable ±80° left-right swivel and ±15° tilt, providing flexible aiming without additional hardware; ten M6 insert points on the back panel accommodate alternative mounting solutions and allow integration with truss systems.

Audio Performance & Coverage

Eight 50mm full-range drivers with dual neodymium magnets and butyl rubber surrounds produce a frequency range of 80 Hz–20 kHz (-10dB) with 93 dB sensitivity in speech mode and 89 dB in music mode. The 20° vertical coverage (1.5 kHz–16 kHz, ±10°) and 150° horizontal coverage (1 kHz–4 kHz, ±20°) ensure focused, controlled sound distribution typical of line array design, giving you predictable coverage at FOH and side positions.
