JBL CBT 70JE-1-WH Extension For CBT 70J-1 Column Speaker, White

The CBT 70JE-1-WH is a purpose-built extension module that stacks directly onto the CBT 70J-1 column speaker, adding 70 cm of vertical coverage without requiring separate mounting infrastructure. This extension preserves the column's tight directional control while expanding throw distance and audience coverage, making it ideal for permanent installations, houses of worship, and venues where vertical stack arrays deliver consistent coverage across multiple zones.

Acoustic Performance

Built with four 125 mm (5 in) high-power LF drivers featuring dual magnet neodymium motors and 38 mm (1.5 in) voice coils, the extension delivers 500W power handling at 8 ohms impedance with extended bass response to 45 Hz. The extended pattern control extends to 400 Hz for ±20° control and to 200 Hz for substantial off-axis cancellation, ensuring tight beam control across the audio spectrum.

Build & Environmental Durability

The fiberglass-reinforced ABS enclosure with coated diaphragm materials resists moisture, UV exposure, and salt spray for outdoor or harsh indoor environments. Achieving IP-55 rating when installed with the optional MTC-PC2 panel cover, the extension withstands 200-hour ASTM G85 acid-air/salt-spray testing, making it suitable for marine, coastal, and demanding outdoor venues.
