Description
JBL CBT 50LA-LS 50cm Tall Line Array Column Speaker with EN54-24 Compliance, Black
The JBL CBT 50LA-LS is a compact line array column speaker built for professional speech reinforcement and life safety applications. Its slim vertical profile and included swivel/tilt bracket make installation straightforward in venues, facilities, and outdoor installations where space constraints demand a compact footprint without sacrificing coverage or output clarity.
Audio Performance & Coverage
Eight 50mm full-range drivers deliver 93 dB sensitivity in speech mode (2 kHz – 14 kHz) and 89 dB in music mode (300 Hz – 18 kHz), with frequency response spanning 120 Hz – 20 kHz at –10dB. The speaker achieves 20° vertical coverage (±10°, 1.5 kHz – 16 kHz) and wide 150° horizontal dispersion (ave, 1 kHz – 4 kHz, ±20°), ensuring even sound distribution across large or irregular spaces during live events and venue installations.
Build & Integration
The cabinet is constructed from fiberglass-reinforced ABS with UV-resistant paint, built to survive both indoor and outdoor touring environments. Ten M6 insert points on the back panel provide flexible mounting options, and the unit includes a swivel/tilt wall-mount bracket; a built-in 70V/100V transformer accommodates distributed audio systems, while direct 8-ohm capability supports traditional amplifier connections for reliable road deployment.

Frequently Asked Questions
What applications is this speaker designed for?
The CBT 50LA-LS is engineered for live speech reinforcement, life safety systems, venue installations, and facilities requiring EN 54-24 compliance. It excels at even sound distribution across large or irregular spaces and is not intended for studio recording or music-focused mixing.
How does the 70V/100V transformer work, and what are my connection options?
The built-in 70V/100V transformer accommodates distributed audio systems common in installed venues and facilities. You can also connect directly to an amplifier using the 8-ohm input, giving you flexibility between traditional amp-driven setups and transformer-based line systems.
What coverage does this column provide, and will it work in an irregular space?
The CBT 50LA-LS delivers 150° horizontal dispersion and 20° vertical coverage (±10°), which means it spreads sound widely left to right while maintaining a narrow top-to-bottom footprint. This makes it ideal for uneven or large spaces where consistent speech intelligibility is critical.
What's the difference between speech and music mode, and how do I switch?
A dedicated Music/Speech voicing switch optimizes the eight 50mm drivers for each application—speech mode emphasizes the 2 kHz–14 kHz range for clarity, while music mode spans 300 Hz–18 kHz for fuller tone. Simply flip the switch depending on whether you're reinforcing a presentation or background music.
What makes this speaker suitable for outdoor or demanding installations?
The cabinet is fiberglass-reinforced ABS with UV-resistant paint to withstand outdoor weather and high-traffic venue environments. Its compact 528 x 99 x 153 mm size, swivel/tilt bracket, and ten M6 mounting insert points make it adaptable to tight spaces, walls, and ceilings without sacrificing durability or coverage.
