Description
The JBL CBT 70JE-1 is the purpose-designed extension for the CBT 70J-1 line array column. It attaches to the top of the CBT 70J-1 with the included coupler plate and adds four 5 in LF drivers and a crossover, which extends bass response to 45 Hz, extends pattern control and raises output. Use it with a CBT 70J-1 (sold separately). This listing is for the white version.
The combined array is a progressive line with asymmetrical vertical coverage that sends more sound to the far areas of the room. The fiberglass-reinforced ABS enclosure has a stronger grille, and the system suits auditoriums, lecture halls, stadiums and theme parks.
