The 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 nCBT-70J Constant Beamwidth Technology™ Two-Way Line Array Column with Asymmetrical Vertical Coverage. With improved mounting bracket for enhanced aiming flexibility and stronger grille. n nThe CBT 70J, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilising complex analogue delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers. nCBT-70J is a J-Array that has a slight downwards tilt. n nFeatures nAsymmetrical vertical coverage sends more sound toward far area of room to make front-to-back sound levels more consistent. nComponents: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers, narranged coaxially. 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. nDynamic SonicGuard™ overload protection of HF devices nSwivel (pan) / tilt wall bracket included. n nJBL PRO VIDEOS: n nDISCUSSING 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
