Frequently asked questions
What frequency ranges does each product cover?
The CBT 70JE-1-WH extension handles midrange through treble with extended bass to 45 Hz, designed to stack with the CBT 70J-1 column. The JBL-GSB12-TN covers 30 Hz–120 Hz exclusively, serving as a dedicated subwoofer for low-end reinforcement only.
Can these products work together in one system?
Yes. The CBT 70JE-1-WH provides directional mid/high coverage while the JBL-GSB12-TN adds buried bass extension beneath the coverage area, creating a complete outdoor or permanent installation system.
Which is better for a concealed outdoor installation?
The JBL-GSB12-TN is specifically designed for in-ground burial with IP66 rating and MilSpec 810 compliance. The CBT 70JE-1-WH must be mounted visibly on the CBT 70J-1 column but offers IP-55 protection when paired with the optional MTC-PC2 panel cover.
What's the difference in power handling?
The CBT 70JE-1-WH handles 500W at 8 ohms impedance, while the JBL-GSB12-TN delivers 450W RMS (1800W peak) with multiple tap options for 70V/100V systems, making the sub better suited for large distributed installations.
