Description
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—sufficient for distributed installations and background playback in commercial spaces. The controlled vertical and horizontal radiation patterns minimize reflections and ensure consistent intelligibility throughout the coverage area.
Design & Environmental Durability
The compact 528 × 99 × 153 mm form factor mounts efficiently on walls or rigging systems without imposing bulk. UV, moisture, and 200-hour ASTM G85 acid-air/salt-spray resistance qualify this speaker for outdoor installation, while the Dynamic SonicGuard™ overload protection safeguards components against transient peaks and thermal stress in continuous-use applications.

What size venue or space is this speaker designed for?
The CBT 50LA-1-WH is engineered for medium to large venues, outdoor events, retail spaces, and distributed installations where consistent intelligible coverage across a defined area is the priority. Its 115 dB continuous SPL (speech mode) and controlled directivity make it suitable for venues ranging from small retail to moderate outdoor events.
Can this speaker handle outdoor installation?
Yes. The speaker is rated for UV, moisture, and salt-spray resistance (200-hour ASTM G85), making it suitable for outdoor and humid environments. Its white finish and environmental durability are designed for long-term exposure.
Does this speaker include a transformer, and what are my wiring options?
Yes, the speaker includes a built-in 70V/100V transformer for distributed systems, and it also supports direct 8-ohm connection. Power capacity is 100W continuous (400W peak) at 100 hours or 150W continuous (600W peak) at 2 hours.
How does the line array design improve coverage compared to a traditional point-source speaker?
The line array's vertical 20° pattern and 150° horizontal dispersion deliver uniform sound across the coverage area without the acoustic dead zones created by point-source designs. This controlled directivity also minimizes unwanted reflections and improves intelligibility throughout the space.
