JBL CBT 70J-1 Overview

The white CBT 70J-1 from JBL is a 2-way line array column loudspeaker, ideal for use in auditoriums, lecture halls, stadiums, theme parks, and more. The unit features four 5" high-power low frequency drivers and sixteen 1" soft dome tweeters to provide plenty of power and a wide frequency response.

The asymmetrical vertical coverage provides consistent front-to-back sound levels, while the patent-pending Constant Beamwidth Technology provides constant directivity and reduces out-of-coverage lobing. The vertical pattern coverage is switchable between 45° and 25°, allowing you to choose the best use for medium-throw or long-throw applications.

Switchable voicing provides a flat response in music mode and a mid-range presence boost in speech mode to accommodate music and speech programs. Built-in SonicGuard technology provides overload protection for HF devices. This model includes an improved mounting bracket that affords enhanced aiming flexibility and a stronger grille.

JBL CBT 70J-1 Reviews

Spot-on performance

By Ken
Rated 5 out of 5
Date: 2023-11-13

I just installed two of these, along with suitable wall treatments, in a gymnasium that was converted into a church auditorium. They perform great. The variable beam width and asymmetrical vertical pattern put the sound where I needed it and kept it off the walls and ceiling. Their size doesn't make them look like speaker arrays - they almost disappear into the room. I added the low frequency extensions to fill out the spectrum. They ARE NOT rock concert speakers. When properly installed in a space, they are a perfect solution to difficult sound control situations. I would install them again in the proper application! So called experts who diss them don't know what they are doing.

Useful for sound people who know what they are doing

Used this product in a number of difficult acoustic situations. Very effective in highly reverberant spaces. Some bone head rocker sound people who don't get physics have no idea how these work so a scared of them 'because they don't have a horn'. Don't listen to those idiots - these speakers are great, and designed by one of the best speaker engineers that has ever lived!

Can I use this on a 70v amp like the JBL CSA ...

Can I use this on a 70v amp like the JBL CSA 1300z?
Asked by: Kyle
The JBL CSA 1300Z Single-Channel 300W Amplifier can operate at 8 ohms, so you can use it to power one JBL CBT 70J-1 Line Array Column Loudspeaker.
