Description
JBL CBT 100LA-LS 100cm Tall Line Array Column Speaker with EN54-24 Certification
The JBL CBT 100LA-LS is a compact, vertically-oriented line array column built for venues and installations where consistent speech intelligibility and music reproduction across distributed audiences matter. Its lightweight fiberglass-reinforced ABS construction and integrated mounting hardware make it straightforward to deploy in permanent or semi-permanent setups. The switchable coverage patterns and voicing modes let you tailor the acoustic response to match different room geometries and application demands without additional processing.
Audio Performance & Coverage
Sixteen 50mm full-range drivers produce a frequency response of 120 Hz–20 kHz (−10dB), with switchable vertical coverage patterns of 40° (medium-throw) or 15° (long-throw) to match your installation depth and how audiences are spread throughout the space. Sensitivity ratings of 96 dB (speech) and 93 dB (music) combined with EN54-certified maximum SPL of 92 dB @ 4 meters deliver reliable speech clarity in emergency systems and commercial audio installations. Dual voicing modes—flat response for music and presence-peaked midrange for speech—optimize intelligibility across different use cases without swapping boxes.
Installation & Electrical Design
The integrated 70V/100V transformer with multi-tap options (15w–120w @ 70V and 30w–120w @ 100V) works with standard distributed audio wiring in existing systems, while direct 8-ohm operation supports low-impedance setups if that's what your rig calls for. Eighteen M6 insert points on the rear panel enable flexible mounting configurations, and the included swivel/tilt wall-mount bracket simplifies angled or stacked deployments. IP-55 rating (with optional MTC-PC2 cover) and EN54-24:2008 certification establish this speaker as dependable for weather-exposed venues and life-safety-certified applications.

Frequently Asked Questions
What does EN54-24 certification mean for my installation?
EN54-24 is a European fire-safety standard for emergency audio systems. This speaker meets that certification, meaning it can be deployed in life-safety applications, healthcare facilities, and venues with strict audio code requirements. The IP-55 rating and UL94-5VB flammability rating reinforce its suitability for regulated environments.
Can I use this for music playback, or is it speech-only?
The CBT 100LA-LS includes a flat voicing mode for music playback and a separate presence-peaked mode optimized for speech. However, its 120 Hz low-end rolloff and speech-optimized tuning make it better suited for intelligibility-critical applications; for full-range music in small intimate venues, you may prefer a different speaker.
What's the difference between the 40° and 15° coverage patterns?
The 40° medium-throw pattern suits smaller to mid-sized venues with closer audience distances, while the 15° long-throw pattern is designed for deeper rooms or distributed installations where the speaker must project audio farther without excessive side-lobe coverage.
Does this work with standard distributed-audio wiring?
Yes. The built-in transformer supports 70V and 100V constant-voltage distributed audio with multiple tap options (15w–120w @ 70V, 30w–120w @ 100V), which is standard for commercial installations. It also supports direct 8-ohm low-impedance operation if needed.
How much does this weigh, and how is it mounted?
The speaker weighs 7.2 kg (15.8 lb) and measures 1000 mm tall, making it compact and lightweight for overhead or wall mounting. The included swivel/tilt bracket and eighteen M6 insert points on the rear panel enable flexible stacked or angled deployments in permanent installations.
