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 degrees 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 degrees for medium-throw coverage and 25 degrees 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 Color: Black Frequency Range ( -10dB): 45 Hz - 20 kHz Impedance: 4 ohms Power Rating: 1000 W ( 4000 W peak), 2 hrs 700 W ( 2800 W peak), 100 hrs Enclosure: Fiberglass-reinforced ABS cabinet, painted aluminum grille. Components - 70JE-1: Four ( 4) 130 mm ( 5 in) LF drivers Frequency Range ( -10 dB) - 70JE-1: 45 Hz - 700 Hz Sensitivity ( 2.83V 1m) - 70JE-1: 90 dB full space, 96 dB half-space ( 65 Hz - 300 Hz) Nominal Impedance - 70JE-1: 8 ohms Power Capacity - 70JE-1: 500 W ( 2000 W
