DESCRIPTION<\/h2>\n

Constant Beamwidth Technology\u2122 Two-Way Line Array Column with Asymmetrical Vertical Coverage. With improved mounting bracket for enhanced aiming flexibility and stronger grille.<\/p>\n

 <\/p>\n

The CBT 70J-1, with Constant Beamwidth Technology\u2122, 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)<\/p>\n

 <\/p>\n

FEATURES<\/strong><\/h4>\n
    \n
  • Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent.<\/li>\n
  • Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers, arranged coaxially.<\/li>\n
  • Patent-pending Constant Beamwidth Technology\u2122 provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.<\/li>\n
  • Vertical pattern coverage switchable between 45\u00b0 for medium-throw coverage and 25\u00b0 forlong-throw applications.<\/li>\n
  • Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.<\/li>\n
  • Dynamic SonicGuard\u2122 overload protection of HF devices<\/li>\n
  • Swivel (pan) \/ tilt wall bracket included.<\/li>\n<\/ul>\n
