JBL CBT 50LA-1-WH 50cm Tall Line Array Column Speaker
The JBL CBT 50LA-1-WH is a compact line array column speaker engineered for consistent, intelligible coverage across medium to large venues. Its vertical 20° pattern and 150° horizontal dispersion deliver uniform sound distribution without the acoustic dead zones typical of point-source designs. Built to withstand outdoor and humid environments, this white-finished unit combines professional durability with straightforward rigging via its included swivel/tilt wall bracket.
Audio Performance & Coverage
Eight 50mm full-range drivers with dual neodymium magnets produce clean output across an 80 Hz–20 kHz frequency range. The speaker achieves 115 dB continuous SPL in speech mode (121 dB peak) and 111 dB in music mode (117 dB peak), with 93 dB sensitivity in speech mode and 89 dB in music mode—ideal for live sound reinforcement and distributed venue applications. The controlled vertical and horizontal radiation patterns minimize reflections and ensure consistent intelligibility throughout the coverage area, critical for speech-heavy events and background music systems alike.
Design & Environmental Durability
The compact 528 × 99 × 153 mm form factor mounts efficiently on walls or rigging systems without imposing bulk, making it practical for permanent installation or mobile deployment. UV, moisture, and 200-hour ASTM G85 acid-air/salt-spray resistance qualify this speaker for outdoor installation and road use, while the Dynamic SonicGuard™ overload protection safeguards components against transient peaks and thermal stress in continuous touring and event applications.

Frequently Asked Questions
What makes this speaker better than a standard point-source design for live venues?
Line array column speakers like this eliminate acoustic dead zones by delivering a uniform sound field across the audience via their controlled 20° vertical and 150° horizontal coverage patterns. This ensures consistent intelligibility and balanced coverage without the hot spots and shadows typical of traditional point-source speakers.
Can this speaker handle outdoor use?
Yes. The CBT 50LA-1-WH features UV, moisture, and salt-spray resistance (200-hour ASTM G85 rated) and is engineered for outdoor and humid environments, making it suitable for patios, exterior venues, and coastal installations.
What connectivity and impedance options does it have?
The speaker includes a built-in 70V/100V transformer for distributed audio systems and supports 8-ohm direct connection. This dual-impedance flexibility lets you wire it into either traditional amplified systems or constant-voltage commercial install networks.
How much SPL does it produce, and is it enough for live sound?
In speech mode it delivers 115 dB continuous (121 dB peak); in music mode, 111 dB continuous (117 dB peak). These levels are suitable for distributed systems, background playback, and speech reinforcement in medium to large venues, though small-venue live music may need additional cabinets or a larger main PA.
What is included with the speaker, and how is it mounted?
The CBT 50LA-1-WH comes with a swivel/tilt wall bracket for easy angle adjustment. Its compact 528 × 99 × 153 mm size allows efficient wall mounting or rigging in tight spaces without imposing visual bulk.
