Product Overview

The JBL CBT 100LA-1 is a Constant Beamwidth Technology line array column loudspeaker built for high-intelligibility speech and program audio in reverberant commercial spaces. With switchable vertical coverage and a built-in 70V/100V transformer, this column array speaker drops cleanly into distributed-line and direct-drive installed audio systems alike. It suits houses of worship, auditoriums, government spaces, and multi-purpose rooms where even coverage and clear speech are essential. The slim black column profile keeps the installation visually unobtrusive on walls and pillars.

Product Description

The CBT 100LA-1 uses sixteen 50 mm (2 in) drivers in a slim column and JBL’s Constant Beamwidth Technology, which applies analog delay beam-forming and amplitude tapering to deliver consistent vertical coverage without the narrow beaming and out-of-coverage lobing typical of conventional column speakers. Vertical pattern coverage is switchable between 40 degrees for medium-throw rooms and 15 degrees for long-throw applications, letting integrators match dispersion to the space. A switchable voicing control selects flat response for music or a mid-range presence peak for speech, so a single column adapts to different program needs. The built-in 70V/100V transformer supports distributed-line installations, while 8-ohm direct drive is also available for low-impedance amplification. Dynamic SonicGuard overload protection helps guard the drivers during demanding use, and the included swivel (pan)/tilt wall bracket allows precise aiming at the audience.

Frequently Asked Questions

Can the CBT 100LA-1 run on a 70V/100V distributed system?
Yes. It has a built-in 70V/100V transformer for distributed-line installations and also supports 8-ohm direct drive for low-impedance amplifier connections.

How do I choose between the 40-degree and 15-degree settings?
Use the 40-degree pattern for medium-throw rooms where the audience is relatively close, and the 15-degree pattern for long-throw applications to project intelligible sound to the back of deeper spaces.

Is it appropriate for speech-heavy applications?
Yes. The switchable speech voicing adds a mid-range presence peak that improves intelligibility, making it well suited to houses of worship, courtrooms, and meeting spaces.

What mounting hardware is included?
A swivel (pan)/tilt wall bracket is included for precise vertical and horizontal aiming during installation.

What amplification or support is available?
Pair it with a 70V/100V or 8-ohm amplifier sized to the system load; Creation Networks can assist with amplifier selection and AV integration.
