The black CBT 1000E Extension Loudspeaker from JBL features six 6.5" low-frequency drivers and a purpose-designed crossover network for use in the CBT 1000 + 1000E system. The drivers feature neodymium magnet motors with 2" diameter voice coils providing maximum flux in a compact package. The magnetic structure is magnetically shielded and the copper pole tips reduce flux modulation and minimize distortion. The 0.62" long coil provides linear drive and high power handling of 1500W in a compact driver.
Each driver features damped blended surrounds and coated sealed paper cones. They are coated with diaphragm materials to provide moisture, UV, and salt resistance for outdoor capability. This extension speaker comes in a tough fiberglass reinforced ABS cabinet. Its thick heavy-duty aluminum grille allows for rust-free installation outdoors. A coupler plate is included for combining this extension speaker with the CBT 1000 array speaker (not included).
