JBL CBT 70JE-1 Designed Extension for CBT 70J-1 Line Array Column Loudspeaker 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. Features: Components: Four 125 mm (5 in) high-power LF drivers (70JE-1) 500 Watt power handling (70JE-1) Built-in purpose-designed crossover network, for combining with CBT 70J-1 (70JE-1) Coupler plate included (70JE-1) Extended pattern control (to 400 Hz for 20 control, to 200 Hz for substantial off-axis cancellation) Extended bass response to 45 Hz. Components: Sixteen 25 mm (1 in) soft dome tweeters and eight 125 mm (5 in) high-power LF drivers. Patent-pending Constant Beamwidth Technology? provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. Vertical pattern coverage switchable between 45 for medium-throw coverage and 25 for long-throw applications. Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode. Coupler plate and wall swivel (pan)/tilt bracket included (rear insert-point pattern fits standard third-party brackets) Specifications: Drivers: Eight (8) 130 mm (5 in) LF drivers Sixteen (16) 25 mm (1 in) HF drivers Frequency Range (-10dB): 45 Hz ? 20 kHz Coverage Angle: Vertical (selectable via switch) Narrow Mode: 25 (2 kHz ? 16 kHz) (10) Broad Mode: 45 (350 Hz ? 16 kHz) (10) Horizontal 150 (500 Hz ? 18 kHz, 20) Sensitivity: Narrow: (speech mode) 98 dB @ 2.83V, 95 dB @ 2.0V (150 Hz ? 8 kHz) (music mode) 94 dB @ 2.83V, 91 dB @ 2.0V (80 Hz ? 18 kHz) Broad: (speech mode) 97 dB @ 2.83V, 94 dB @ 2.0V (100 ? 8 kHz) (music mode) 93 dB @ 2.83V, 90 dB @ 2.0V (70 Hz ? 18 kHz) Impedance: 4 ohms Power Rating: 1000 W (4000 W peak), 2 hrs 700 W (2800 W peak), 100 hrs Maximum SPL (1m): Narrow: (speech mode) 125 dB cont ave (131 peak) (music mode) 121 dB cont ave (127 peak) Broad: (speech mode) 124 dB cont ave (130 peak) (music mode) 120 dB cont ave (126 peak) Low Frequency Drivers: 8 pcs, 130 mm (5 in) drivers, dual magnet neodymium, 38 mm (1.5 in) voice coil, damped blended textile surround, coated diaphragm for moisture, UV and salt resistance, shielded.
