Description
The J-shape of the array works in conjunction with the Constant Beamwidth Technology circuitry to provide asymmetrical coverage similar to that of expensive line arrays commonly used in concert systems. The J column sends highly concentrated sound toward the back of the venue, while down-filling a broader, less concentrated sound to the front of the venue. This results in more consistent sound levels from front to back. 70 cm J-shaped coaxial line array with 16 x 1″ tweeters, 4 x 5″ woofers plus patent-pending Constant Beamwidth Technology™ circuitry. Perfect for A/V, Small Performance Auditoriums, Classrooms, Lecture Halls. For Outdoor Applications: Pole-Mounted at School Stadiums, Racetracks, Theme Parks, Fill Applications.

Had this as a gift and solid product. Would be perfect if it came in more color options.

Went ahead and got this after doing some research and i’m amazed at the quality for this price point. Very satisfied with the JBL CBT 70J Constant Beamwidth Technology Line Array Column Loudspeaker (Black). Feels much more expensive than it is. Exactly what I needed.
