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

Product Overview

The JBL CBT 1000-WH is a two-way line array column loudspeaker with Constant Beamwidth Technology™, engineered for high-intelligibility sound reinforcement in acoustically challenging commercial spaces. Its adjustable vertical coverage lets integrators tune dispersion to the room, making this column loudspeaker well suited to houses of worship, auditoriums, and large multi-purpose rooms with long reverberation times. With switchable directivity and voicing, the CBT 1000 delivers clear speech and program audio without the complexity of a full line array system. The included swivel wall bracket and white finish support clean architectural integration.

Product Description

The CBT 1000-WH is a high-output column array built around six 165 mm (6.5 in) neodymium LF drivers and twenty-four 25 mm HF drivers, delivering controlled vertical dispersion that focuses sound on the audience and away from reflective ceilings and walls. JBL's Constant Beamwidth Technology™ maintains consistent coverage across the frequency range, a key advantage for speech intelligibility in reverberant rooms. Front-panel switches select directivity patterns (separate top and bottom selections) and voicing modes for speech or music, allowing one loudspeaker to adapt to different applications without external processing. The fiberglass-reinforced ABS enclosure and coated, moisture/UV/salt-resistant drivers make it durable enough for semi-exposed installations, and it carries an IP-55 rating when fitted with the optional MTC-PC2 cover. With 1500 W power capacity and up to 137 dB peak SPL, the CBT 1000-WH provides substantial headroom for large venues. The included two-part swivel (pan/tilt) wall bracket and fourteen rear M8 inserts give integrators flexible aiming and suspension options for permanent commercial installation. This makes the CBT 1000 a practical alternative to a full line array where intelligibility, adjustable coverage, and clean aesthetics matter.

Frequently Asked Questions

How does the CBT 1000 differ from a traditional line array?
The CBT 1000 is a self-contained column that uses Constant Beamwidth Technology and front-panel switches to set vertical coverage and voicing, delivering line-array-style intelligibility without the rigging, amplification channels, and DSP complexity of a multi-box array.

Can I adjust the vertical coverage for my room?
Yes. The column provides separate top and bottom directivity selections, letting you narrow or widen vertical dispersion to focus energy on the audience and reduce reflections off ceilings and rear walls.

Is it suitable for outdoor or semi-exposed installations?
The drivers are coated for moisture, UV, and salt resistance, and the system is IP-55 rated when installed with the optional MTC-PC2 cover, making it appropriate for covered exterior and high-humidity environments.

What mounting and suspension options are available?
It ships with a two-part pan/tilt wall bracket and includes fourteen rear M8 inserts plus top and bottom end-cap inserts, supporting wall mounting, third-party brackets, and overhead suspension with the optional suspension kit.

What amplification does it require?
The CBT 1000-WH is a passive 4-ohm loudspeaker rated for 1500 W program power; pair it with an appropriately rated amplifier and apply the recommended 35 Hz high-pass for driver protection. Creation Networks can assist with amplifier and system specification.
