A versatile line-array speaker

The JBL CBT 70J-1 offers a lot of handy options in placement, aiming, dispersion angle and voicing. It features four 5-inch low frequency drivers and sixteen 1-inch high frequency drivers in a line array. It offers switchable voicing for music or speech applications. Constant Beamwidth™ technology provides constant directivity throughout the speaker's frequency response range, giving you more consistent sound throughout the listening area..

Coverage angle options

The speaker's asymmetrical vertical coverage sends more sound toward the far side of your room to make front-to-back sound levels more consistent. You can select a 25-degree dispersion angle in narrow mode for long-throw vertical coverage, or a 45-degree dispersion angle in wide mode for medium-throw coverage. Horizontal coverage is 150 degrees.

Pan/tilt mounting options

The included bracket lets you aim coverage even more accurately. It can swivel left/right up to 80-degrees (when no tilt is engaged), or tilt up to 15-degrees up and down.
