JBL CBT 70J Line Array Column Loudspeaker (Black)

Description

The JBL CBT 70J Line Array Column Loudspeaker 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-ofcoverage lobing that are typical of straight form-factor column speakers. The CBT 70J combines Constant Beamwidth Technology with a physical J-shaped curving, resulting in a very well controlled progressive line array with asymmetrical vertical coverage. The asymmetrical coverage produces a higher concentration of sound with a tighter pattern from the upper half of the array and a lower concentration of sound with a broader vertical pattern from the lower half of the array. This sends more sound toward the far area of the room than to the near area of the room, resulting in more even front-to-back SPL levels than would be the case from a traditional speaker or column that projects symmetrically in the vertical plane.

The two-way coaxial design provides a wide 60 Hz – 20 kHz bandwidth. The low-diffraction baffle eliminates frequency response irregularities that could otherwise occur due to baffle discontinuities. The slim, compact design fits well into virtually any architectural decor. The 70 cm tall line array height provides consistent pattern control throughout the intelligibility band, making the CBT 70J work well in difficult acoustic environments.

Main Features

• Ideal for use in auditoriums, lecture halls, stadiums, theme parks, and more
• Four 130mm high-power low frequency drivers and sixteen 25mm soft dome tweeters provide plenty of power and a wide frequency response
