The black CBT 70JE-1 Extension for CBT 70J-1 Speaker by JBL Professional is purposely designed for use with the CBT 70J-1, in a tough ﬁberglass-reinforced ABS enclosure. The speaker contains four low frequency drivers and a crossover network. The 500 W power handling and high sensitivity delivers powerful low frequency output.
When connected to a CBT 70J-1 speaker, the CBT 70JE-1 Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology, which results in pattern control consistency.
The CBT 70JE-1 attaches to the top of the CBT 70J-1, utilizing the included coupler plate, resulting in a well controlled progressive line array with asymmetrical vertical coverage. This coverage produces a higher concentration of sound with a tighter pattern projecting to the far areas of the listening space.
