The JBL 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.
When connected to a CBT 70J-1 line array column speaker, the CBT 70JE-1 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 70JE-1 attaches to the top of the CBT 70J-1, utilizing the included coupler plate, resulting in a very well controlled progressive line array with asymmetrical vertical coverage. This coverage produces a higher concentration of sound with a tighter pattern projecting to the far areas of the listening space, and a lower concentration with a broader vertical pattern projecting toward the near area of the space. This results in more even front-to-back SPLlevels than would be the case from a traditional speaker or column that projects symmetrically.
