Extension for CBT 1000 Line Array Column Speaker

When connected to a CBT1000 line array column speaker, the 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, utilizing complex analog beamforming 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 CBT 1000E cabinet contains six low frequency drivers and a crossover network purposely designed for use in the CBT 1000 + 1000E system, in a tough fiberglass-reinforced ABS enclosure. The 1500W power handling and high sensitivity delivers powerful low frequency output. The drivers have neodymium magnet motors with 50 mm (2 in) 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.
