JBL CBT 1000E-WH Extension for CBT 1000 Column Speaker, White
The CBT 1000E-WH is a purpose-built low-frequency extension module designed to expand the sonic capability of the CBT 1000 column speaker system. This white extension cabinet integrates seamlessly with the CBT 1000, adding substantial bass output and extending the system's frequency response into the critical lower midrange and sub-bass regions. The installation is straightforward with M8 threaded inserts, making it a practical addition for venues and installations requiring deeper low-end reinforcement.
Audio Performance & Output
The extension delivers 1500W power handling with an impressive maximum SPL of 130 dB in half-space configuration (65 Hz – 300 Hz), ensuring powerful, controlled bass reproduction that cuts through on stage and maintains clarity at distance. Sensitivity ranges from 95 dB to 102 dB depending on setting selection, allowing flexible integration with existing audio systems and venues of varying sizes. When paired with the CBT 1000, this extension achieves an extended frequency response of 38 Hz to 20 kHz, providing full-spectrum coverage for demanding live sound and touring applications.
Driver Design & Durability
Six 165 mm (6.5 in) high-excursion low-frequency drivers with neodymium magnet motors and 50 mm (2 in) diameter voice coils form the core of this extension. The drivers feature damped blended surrounds and coated diaphragms engineered for resistance to moisture, UV light, and salt spray, making this cabinet reliable for both indoor venues and outdoor gigs. All components are housed in a rigid fiberglass-reinforced ABS enclosure designed to withstand the road and deliver consistent performance night after night.
