JBL CBT 70JE-1 Extension for CBT J-1 Speaker (Black)

Powerful Extension for Enhanced Sound Output
The JBL CBT 70JE-1 Extension Module is a purpose-designed companion for the CBT 70J-1 speaker, engineered to deliver extended bass response, enhanced pattern control, and increased sound output levels. Housed in a tough fiberglass-reinforced ABS enclosure, this module features four low-frequency drivers and an integrated crossover network, making it an essential addition for applications requiring superior audio performance in large spaces.

Seamless Integration for Improved Bass and Coverage
When paired with the CBT 70J-1, the CBT 70JE-1 extends the system's bass response down to 45 Hz, creating a rich, full sound. The combined system leverages JBL's Constant Beamwidth Technology to maintain consistent directivity and reduce unwanted out-of-coverage lobing. This integration provides a progressive line array with asymmetrical vertical coverage, ensuring even sound levels across near and far areas of the listening space.

Enhanced Vertical Coverage for Large Spaces
Designed with large venues in mind, the CBT 70JE-1 extends the vertical pattern control to lower frequencies. This ensures precise audio targeting, delivering tight, well-directed sound to the farthest reaches of auditoriums, lecture halls, stadiums, and theme parks. The module's design offers substantial off-axis cancellation for frequencies as low as 200 Hz, ensuring a clean and focused sound field.

Durable Construction for Long-Term Reliability
The fiberglass-reinforced ABS enclosure is built to withstand rigorous use in demanding environments. Whether used indoors or outdoors, the CBT 70JE-1 offers long-term durability and reliability, making it a versatile solution for a variety of professional sound reinforcement applications.

Simple Installation with Included Coupler Plate
Attaching the CBT 70JE-1 to the CBT 70J-1 is straightforward, thanks to the included coupler plate. This ensures a secure connection and allows the system to function as a unified line array, providing enhanced sound performance with minimal effort during setup.
