JBL CBT 70J-1 Line Array Column Loudspeaker (White)

Passive Column Array with Switchable Coverage and Constant Beamwidth Technology

The JBL CBT 70J-1 is a white, 2-way passive line array column loudspeaker designed for professional installed sound applications. Its controlled coverage and slim column format make it suitable for auditoriums, lecture halls, stadiums, theme parks, and other spaces requiring clear, consistent sound distribution.

Four 5-inch high-power low-frequency drivers and sixteen 1-inch soft-dome tweeters provide a frequency response from 60 Hz to 20 kHz. JBL Constant Beamwidth Technology maintains consistent directivity while reducing unwanted out-of-coverage lobing, and the asymmetrical vertical pattern directs more sound toward distant listening areas for improved front-to-back consistency.

Installers can switch the vertical coverage between a 25-degree narrow pattern for longer-throw applications and a 45-degree broad pattern for medium-throw coverage. Selectable music and speech voicing provides either a flat response or enhanced midrange presence, allowing the loudspeaker to support different program requirements within permanent sound systems.

The CBT 70J-1 operates at a nominal 8-ohm impedance and includes two push-terminal inputs. An included swivel and tilt wall bracket provides flexible aiming, while ten rear M6 mounting points support compatible installation and suspension configurations.

System Integration

The JBL CBT 70J-1 integrates into professional passive loudspeaker systems using an amplifier capable of supporting its 8-ohm nominal impedance and power requirements. Two push-terminal inputs simplify loudspeaker wiring, while selectable coverage and voicing controls allow installers to configure the system for the room, listening area, and program material. The included wall bracket provides continuously variable left-to-right swivel and adjustable vertical tilt for accurate aiming.

Broadcast Workflow Benefits

Controlled directivity helps system designers place sound where it is needed while reducing energy outside the intended listening area. The asymmetrical vertical pattern supports more consistent sound levels from the front to the rear of a venue, while switchable speech and music modes make it easier to adapt the loudspeaker for spoken presentations, announcements, and music playback.
