JBL / CBT 70J-1-WH column speaker system

The CBT 70J-1-WH is a column speaker. Each driver is precisely controlled to equalize sound pressure differences over distance. It features a 2-way configuration with 16 high-frequency tweeters and four 5-inch low-frequency drivers arranged coaxially. It achieves a maximum sound pressure level of 125dB. Its unique CBT technology delivers clear sound throughout the entire area. It is available in white.

Equipped with four low-frequency drivers and 16 high-frequency drivers.

- Coaxial 2-way configuration with four low-frequency drivers and 16 high-frequency drivers using neodymium magnets. Delivers powerful sound from any music source.
- Proprietary CBT technology delivers clear sound regardless of the listening area.
- J-shaped design with asymmetric vertical dispersion. Increases sound pressure levels in the distance and minimizes differences in sound pressure due to distance from the speaker.
- Vertical dispersion can be set to 25° (Narrow) or 45° (Broad).
- Equipped with a Music/Speech switch that changes mid-range sensitivity.
- Wall mounting bracket with adjustable angle (up, down, left, right).
