The white 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.
Ideal for use in auditoriums, lecture halls, stadiums, theme parks, and more
Extended bass response to 45 Hz
Extended pattern control (to 400 Hz for +/- 20° control, to 200 Hz for substantial off-axis cancellation)
