JBL CBT 1000E System CBT 1000E Line Array Column Speaker – White

CBT1000E White

The CBT1000 + CBT1000E White combined line array column system is a high-performance modular loudspeaker solution engineered to deliver extended low-frequency performance, increased acoustic output, and superior pattern control for large and acoustically demanding environments. When the CBT1000E extension cabinet is coupled with the CBT1000 main column, the system forms a unified full-range array that significantly enhances bass depth, vertical pattern control, and overall sound pressure capability.

Powered by Constant Beamwidth Technology™, this integrated system uses advanced analog beamforming and amplitude tapering techniques to achieve consistent vertical coverage while eliminating narrow beaming, uneven dispersion, and off-axis lobing typically associated with conventional passive column speakers. The result is smooth, controlled sound distribution across near-field and far-field listening areas with exceptional clarity and intelligibility.

The combined array integrates twenty-four 25 mm (1 in) extra-high-power soft dome tweeters and twelve 165 mm (6.5 in) high-excursion low-frequency drivers, creating a powerful full-range system capable of delivering deep, controlled bass response extending below 38 Hz. This configuration allows single-array room coverage at high SPL levels with minimal acoustic overspill, making it ideal for large auditoriums, worship spaces, transport terminals, convention halls, performance venues, and large public installations.

The CBT1000 section provides fully adjustable vertical dispersion with four “Pattern Up” and four “Pattern Down” angle selections, enabling sixteen distinct coverage configurations without the need for external DSP processing. This allows precise acoustic tailoring to match room geometry, seating layouts, and architectural constraints.

The patented Tapered Horizontal Waveguide technology delivers continuously variable horizontal dispersion—wide for short-throw coverage and narrower for long-throw projection—ensuring balanced sound distribution across both front and rear listening zones.

With switchable voicing modes for speech and music, high SPL performance capability, integrated crossover design, rugged fiberglass-reinforced ABS construction, and a precision mechanical coupling system, the CBT1000 + CBT1000E White array system provides a complete, scalable, and architecturally refined audio solution for professional large-scale sound reinforcement applications.
