JBL Professional CBT 70JE-1 Extension Loudspeaker overview


Manufacturers Product Description

The CBT 70JE-1 cabinet contains four low frequency drivers and a crossover network purposely designed for use in the CBT 70J-1 + 70JE-1 System, in a tough fiberglass-reinforced ABS enclosure. The 500W power handling and high sensitivity delivers powerful low frequency output.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. The thick, heavy-duty aluminum grille stands up to portable/event applications while allowing for rust-free installation outdoors.
