CBT 70J-1 + 70JE-1 Array System with Constant Beamwidth Technology

The combined array system provides Constant Beamwidth Technology, which represents a breakthrough in pattern control consistency, utilizing complex analog beam- forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of passive column speakers.

The JBL CBT 70JE-1 attaches to the top of the CBT 70J-1, utilizing the included coupler plate, resulting in a very well controlled progressive line array with asymmetrical vertical coverage. This coverage produces a higher concentration of sound with a tighter pattern projecting to the far areas of the listening space, and a lower concentration with a broader vertical pattern projecting toward the near area of the space. This results in more even front-to-back SPL levels than would be the case from a traditional speaker or column that projects symmetrically.

The CBT 70J-1 + 70JE-1 System provides a wide 45 Hz – 20 kHz bandwidth, and the slim footprint fits well into virtually any architectural décor. The 140 cm (55.2 in) tall line array height provides consistent pattern control throughout the intelligibility band, making the System work well in difficult acoustic environments.

• Extended pattern control (to 400 Hz for ± 20° control, to 200 Hz for substantial off-axis cancellation)
• Extended bass response to 45 Hz
• Components: Sixteen 25 mm (1 in) soft dome tweeters and eight 125 mm (5 in) high-power LF drivers
• Patent-pending Constant Beamwidth TechnologyTM provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing
• Vertical pattern coverage switchable between 45° for medium-throw coverage and 25° for long-throw applications
• Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode
• Coupler plate and wall swivel (pan)/tilt bracket included (rear insert-point pattern fits standard third-party brackets)
