JBL Cbt 70JE-1-WH Extension For Cbt 70J-1 Column Spk, Wht
Description
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 the go-to choice for sound engineers and system designers running 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 and predictable behavior in tight or oddly-shaped rooms.
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, so you can depend on it at marine, coastal, and demanding outdoor venues without compromise.

Frequently Asked Questions
What does this extension add to the CBT 70J-1 base speaker?
The CBT 70JE-1-WH adds 70 cm of vertical stacking height to the CBT 70J-1, expanding coverage throw and audience area while preserving the column's tight directional control. It includes four 125 mm high-power LF drivers, 500W power handling, and extended bass response to 45 Hz.
Is this extension weatherproof for outdoor use?
Yes. The fiberglass-reinforced ABS enclosure resists moisture, UV exposure, and salt spray, achieving IP-55 rating when paired with the optional MTC-PC2 panel cover. It passes 200-hour ASTM G85 acid-air and salt-spray testing, making it suitable for marine, coastal, and demanding outdoor venues.
What is the directional control like across the frequency spectrum?
Extended pattern control reaches 400 Hz for ±20° tight beam control, with substantial off-axis cancellation extending to 200 Hz. This ensures consistent directional focus across multiple zones in permanent installations and houses of worship.
How does the extension physically connect to the base speaker?
The extension uses a linking bracket designed for CBT 70J-1 integration and includes a coupler plate with twelve M6 mounting points for eyebolts or swivel clips, allowing straightforward mechanical coupling without separate mounting infrastructure.
What are the electrical specifications?
The extension handles 500W power at 8 ohms impedance and features dual-magnet neodymium motors with 38 mm voice coils and 16 mm long coils for enhanced driver geometry.
