JBL CBT 70J-1 Constant Beamwidth Technology Two Way Line Array Column with Asymmetrical Vertical Cove BLACK

JBL CBT 70J-1 | Constant Beamwidth Technology Two Way Line Array Column with Asymmetrical Vertical Cove BLACK

The JBL CBT 70J-1 stands as a beacon of advanced audio engineering designed to revolutionize sound distribution in medium to large venues. This sophisticated line array column leverages Constant Beamwidth Technology (CBT) to offer unprecedented vertical coverage consistency, ensuring uniform sound levels from the front to the back of the room. Unlike traditional column speakers that struggle with narrow vertical beaming and lobing outside the coverage area, the CBT 70J-1’s complex analog delay beam-forming and amplitude tapering technologies deliver smooth, even sound dispersion. Whether mounted on stage or used for public address in large halls, the CBT 70J-1 assures impeccable audio fidelity and extensive coverage without compromising sound quality.

Equipped with an array of high-power, neatly arranged drivers, this column speaker is capable of addressing diverse acoustic needs with ease. Its dual voicing feature allows for a flat response ideal for music or a mid-range presence boost for speech applications. Remarkably versatile, the vertical pattern coverage can be switched between 45 degrees for medium-throw and 25 degrees for long-throw scenarios. Dynamic SonicGuard technology protects the high-frequency drivers from overload, while its robust, IP-54 rated, water-resistant enclosure makes it suitable for both indoor and outdoor applications.
