JBL CBT 100LA-1 Constant Beamwidth Technology Line Array Column Loudspeaker (White)

The JBL CBT 100LA-1-WH is a column loudspeaker that applies Constant Beamwidth Technology to keep every seat in the house on the same page. Whether you are equipping a lecture hall, a modern sanctuary, or an airport concourse, it delivers consistent intelligibility so the back row hears exactly what the front row does.

The housing measures 39.4 inches in height and maintains a slim profile that fades into architectural spaces. Inside are sixteen full range 2-inch drivers built with neodymium magnets. An internal switch lets you choose a 40-degree vertical beam when you need coverage for a broad seating area, or tighten the pattern to 15 degrees for a longer throw. Installers can fine-tune the array to suit room shape without adding extra speakers.

A selectable Music or Speech setting adjusts the voicing in seconds. Use Music mode when you want fuller low-end response for playback, then flip to Speech mode to bring spoken word into sharp focus for presentations, sermons, or guided tours.

The system handles peaks up to 1300 watts and reaches 127 dB without losing clarity. Built-in protection circuits guard the drivers against overload, so you can push the level when the program demands it and still maintain clean output.

Flexible power options make the speaker at home in distributed sound systems. A built-in transformer supports 70-volt and 100-volt lines, while an 8-ohm bypass is available for direct connection to conventional amplifiers. An IP55 rating confirms resistance to rain and dust, so the same speaker that excels in a boardroom can also serve on an outdoor patio or along a theme-park walkway.

Installation is straightforward. The included wall bracket tilts and swivels, allowing precise aim toward the audience. Once set, the column blends into its surroundings, leaving visitors to focus on the content instead of the equipment.
