JBL 被动分频CBT系列线阵柱能提供前所未有的方向性控制、声音保真度和承受能力，它以运用了JBL专利的恒定束宽电路技术为显著特色，这将是控制模式上的重大突破。即使在困难的声学环境下，CBT线阵柱也能提供一贯不变的方向性覆盖和高超的音频清晰度。
应用CBT系列线阵柱的场所包括：演唱会，交通指挥中心，演讲厅，多功能会议室，商店，审判厅，主题公园，教堂，影院大堂，支持音频的视频，比赛场，以及其他许多项目。
CBT系列50LA线阵柱是一个非常紧凑的50厘米高的高柱，采用直线8-2英寸驱动器；而高大的CBT系列100LA线阵柱达100厘米高，利用16-2英寸驱动器和325瓦处理器，当持续超功率运转时，它将会亮起粉红色灯并发出提示声音。结合恒定束宽电路技术，两款线阵柱都提供恒定的方向性覆盖，并含有低饱和变压器，这样他们就可以作为低阻抗扬声器使用。
另外，CBT系列线阵柱还包括70J型，它的高度为70厘米，是2路同轴线阵列，内置16个软圆顶高音和4个高功率的5英寸低音喇叭。
CBT系列包括50LA，100LA，70J，70JE
CBT 70J+70JE System
When connected to a CBT 70J line array column speaker, the CBT 70JE Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology™, which represents a breakthrough in pattern control consistency, utilizing complex analog beamforming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of passive column speakers.
