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

The JBL CBT 50LA-1 is a compact line array speaker engineered for consistent, even coverage across medium-sized venues and installations. Its slender 50cm profile delivers surprisingly controlled directional performance, making it an efficient choice for speech reinforcement, background music, and distributed audio systems where space and aesthetic integration matter.

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 mounting in tight spaces or above-ceiling installations. 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.

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.
