JBL CBT 1000 Two-Way Line Array Column Loudspeaker with Constant Beamwidth Technology (Black)

Product Overview

The JBL CBT 1000 is a two-way line array column loudspeaker with Constant Beamwidth Technology, engineered for high intelligibility in acoustically challenging spaces. Its adjustable vertical coverage concentrates sound on the audience and away from reflective ceilings and floors, making it well suited to houses of worship, auditoriums, and reverberant multi-purpose rooms. As an installed line array column, it delivers speech clarity and musical program from a slim architectural profile.

Product Description

The CBT 1000 uses a column of transducers with Constant Beamwidth Technology to maintain consistent directivity across its frequency range, reducing the comb-filtering and uneven coverage common to simpler column speakers. Switchable settings let integrators choose between broader and tighter vertical patterns and adjust tonal balance for the room. It operates passively and is driven by an external commercial amplifier, and it can be extended with the matching CBT 1000E module for greater throw and output. The slim black enclosure mounts flat to walls for a low visual profile. Explore related models in the JBL Professional passive PA speakers collection.

Can the CBT 1000 be expanded? Yes. It pairs with the matching CBT 1000E extension module to increase throw and output.

Does it require an external amplifier? Yes. The CBT 1000 is passive and must be driven by a commercial-grade amplifier sized to the application.

How is it mounted? The slim column mounts flat to a wall for a low-profile architectural appearance; confirm bracket and rigging options for your installation.
