JBL CBT 70J-1 - 70 cm J-Shaped Coaxial Line Array BLACK


Constant Beamwidth Technology™ Two-Way Line Array Column with Asymmetrical Vertical Coverage. With improved mounting bracket for enhanced aiming flexibility and stronger grille.
The CBT 70J-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog 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. (shown with included grille removed)
FEATURES
  • Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent.
  • Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers,
    arranged coaxially.
  • 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.
  • Dynamic SonicGuard™ overload protection of HF devices
  • Swivel (pan) / tilt wall bracket included.
