JBL CBT-1000E High Output Extension For CBT-1000 Line Array Column Speaker

Description

The JBL CBT-1000E High Output Extension For CBT-1000 Line Array Column Speaker contains six low frequency drivers and a crossover network purposely designed for use in the CBT 1000 + 1000E system, in a tough fiberglassreinforced ABS enclosure. The 1500W power handling and high sensitivity delivers powerful low frequency output.

The drivers have neodymium magnet motors with 50 mm diameter voice coils. The magnet system provides maximum flux in a compact package. The magnetic structure is magnetically shielded and the copper pole tips reduce flux modulation and minimize distortion. The 16 mm (0.62 mm) long coil provides higher linear drive and high power handling in a compact driver. The drivers feature damped blended surrounds and coated sealed paper cones found in high performance large format drivers. Drivers feature coated diaphragm materials to provide moisture, UV and salt resistance for outdoor capability. The thick heavy-duty aluminum grille allows for rust-free installation outdoors.

CBT 1000 + 1000E Array System

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 tall line array height provides consistent pattern control throughout the intelligibility band, making the System work well for difficult acoustic environments.
