Column Speaker Arrays

The JBL CBT 100LA-1 represents a breakthrough in pattern control consistency to accomplish superior, consistent vertical coverage.

The JBL CBT 50LA-1 line array column loudspeaker features JBL's patent-pending Constant Beamwidth Technology™ that provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.

The CBT 50LA-LS, with Constant Beamwidth Technology, represents a breakthrough in pattern control, utilizing analog delay beamforming and amplitude tapering to accomplish consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers.

The JBL CBT 100LA-1 represents a breakthrough in pattern control consistency to accomplish superior, consistent vertical coverage.

The JBL CBT 70JE-1 cabinet contains four low frequency drivers and a crossover network purposely designed for use with the CBT 70J-1.

The JBL CBT 70J-1 represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage.

When connected to a CBT1000 line array column speaker, the JBL CBT1000E Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology™, which represents a breakthrough in pattern control consistency.

The JBL-CBT 70J-1 + 70JE-1 is a combined array system that provides Constant Beamwidth Technology™ which represents a breakthrough in pattern control consistency.

The JBL CBT1000 full-range cabinet and CBT1000E extension cabinet provide versatile, adjustable vertical pattern selections for aligning the coverage to the geometry of a room. Vertical pattern coverage is individually adjustable through a range of four (4) "Pattern Up" angles and four (4) "Pattern Down" coverage angles for a total of sixteen (16) different coverage combinations, all without the use of external DSP processing.
