Line Array Column Loudspeakers Featuring JBL’s Patent-Pending Constant Beamwidth Technology CBT 50 LA Compact Speech & Music CBT 100 LA Pattern Control Speech & Music CBT 70 J Full-Range J-Shaped CBT 70 JE LF & Pattern Extension
The JBL CBT Series with Constant Beamwidth Technology Ushering in a new era for passive column speaker technology based on years of extensive research conducted by Harman engineers, the JBL CBT Series line array columns with Constant Beamwidth Technology break new ground in performance, versatility, and affordability.
The Revolutionary Advantages of Asymmetrical Vertical Coverage The J-shape of the array works in conjunction with the Constant Beamwidth Technology circuitry to provide asymmetrical coverage similar to that of expensive line arrays commonly used in concert systems. The J column sends highly concentrated sound toward the back of the venue, while down-filling a broader, less concentrated sound to the front of the venue. This results in more consistent sound levels from front to back.
Adjustable Coverage to Fit the Application For the first time ever in a passive column loudspeaker, the coverage pattern of the CBT models can be adjusted with a simple switch. This allows the CBT to meet the requirements of a very broad range of applications. Broad Coverage Mode is excellent for mid-throw situations. Narrow Coverage Mode is for long-throw applications.
