JBL CBT 1000 + CBT 1000E System Column Speaker System for Installation
with Constant Beamwidth Technology

When connected to a CBT 1000 line array column speaker, the CBT 1000E 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, utilizing complex analog beamforming to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of passive column speakers.

The CBT 1000E attaches to the bottom of the CBT 1000 utilizing the included coupler plate, or to the top of the CBT 1000 (when adding the optional MTC-CBT-OSB3 off-set bracket to align the front grilles), resulting in a very well controlled progressive line array with asymmetrical vertical coverage capability. When in one of the asymmetrical settings, the speaker system produces a higher concentration of sound with a tighter pattern projecting toward the far areas of the listening 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 1000 + 1000E System provides a wide 38 Hz – 20 kHz bandwidth, and the slim footprint fits well into virtually any architectural décor. The 2040 mm (80.4 in) tall line array height provides consistent pattern control throughout the intelligibility band, making the System work well for difficult acoustic environments.

• Components: Twenty-four (24) 25 mm (1 in) extra-high-power soft dome tweeters and twelve (12) 165 mm (6.5 in) high-excursion LF drivers
• Very high sound levels up to 131 dB (137 dB peaks) depending on the settings
• 3000 Watt RMS power handling
• Extended pattern control (to 300 Hz for +/- 20 degree control, to 200 Hz for substantial off-axis cancellation)
• Extended bass response to 38 Hz
• Patent-pending Constant Beamwidth Technology™ provides constant directivity and reduces out-of-coverage lobing
• 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
• Patent-pending Tapered Horizontal Waveguide provides a continuously varying horizontal dispersion (very wide for short-throw, narrower for long-throw) delivering superior coverage in both the front and rear corners of a room
• Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode
• 2-piece swivel (pan)/tilt wall bracket and coupler plate included (rear insert-point pattern fits standard third-party brackets)
