JBL CBT 70JE-1 Line Array Column Loudspeaker Extension with Four 125mm Drivers, White

The JBL CBT 70JE-1 line array column speaker extension (White) 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 drivers have lightweight dual magnet neodymium motors with 38 mm (1.5 in) diameter voice coils.

The dual-magnet system provides maximum flux in a compact package. The magnet structure is magnetically shielded and the pole tips are magnetically saturated for lower flux modulation and minimum distortion. The 16 mm (0.63 in) long coils provides high 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.
