CBT-70JE is a Purpose-Designed Extension for CBT 70J Line Array Column Speaker. With stronger grille. n nWhen connected to a CBT 70J line array column speaker, the CBT 70JE 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, utilising complex analogue 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. n nThe CBT Series (Constant Beamwidth Technology) are two-way line array column loudspeakers that are designed for venues that would typically use larger point-and-shoot speakers. n nThe CBT Series is especially beneficial in venues with tricky acoustics or buildings that require discreet sound reinforcement, such as historical sites. The CBT beamforming and amplitude tapering technology allows for an even coverage of sound from the front to the back of the venue, effectively reducing the volume needed by a conventional loudspeaker to cover the same area. n nFeatures nComponents: Four 125 mm (5 in) high-power LF drivers (70JE-1) n500 Watt power handling (70JE-1) nBuilt-in purpose-designed crossover network, for combining with CBT 70J-1 (70JE-1) nCoupler plate included (70JE-1) nExtended pattern control (to 400 Hz for ± 20° control, to 200 Hz for substantial off-axis cancellation) nExtended bass response to 45 Hz. nComponents: Sixteen 25 mm (1 in) soft dome tweeters and eight 125 mm (5 in) high-power LF drivers. nPatent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. nVertical pattern coverage switchable between 45° for medium-throw coverage and 25° for nlong-throw applications. nSwitchable voicing provides flat response in music mode or mid-range presence peak in speech mode. nCoupler plate and wall swivel (pan)/tilt bracket included (rear insert-point pattern fits standard nthird-party brackets) n nJBL PRO VIDEOS: n nEXPLORE CONSTANT BEAMWIDTH TECHNOLOGY IN CBT PASSIVE COLUMNS n n nAN INFORMATIVE OVERVIEW OF THE CBT RANGE AND SPECS n n nEXPLORING SPEECH INTELLIGIBILITY AND STI INDEX n n nJBL PROFESSIONAL CONTROL CONTRACTOR LOUDSPEAKERS UNIQUE DESIGN and PERFORMANCE n
