Frequently asked questions
Can I use these two products together?
No. The CBT 70JE-1 is an extension module for the CBT 70J-1 column speaker, designed for stacked indoor arrays. The JBL-GSB12-TN is a standalone in-ground subwoofer for outdoor landscape systems. They serve entirely different installation types.
Which one handles outdoor weather?
Only the JBL-GSB12-TN is rated for outdoor use, with IP66 weather rating and MilSpec 810 compliance. The CBT 70JE-1 is designed for indoor professional installations like venues and theaters and lacks outdoor environmental protection.
What is the frequency range difference?
The CBT 70JE-1 covers 45 Hz–20 kHz with mid-range clarity and directional control. The JBL-GSB12-TN is limited to 30 Hz–120 Hz, functioning purely as a subwoofer for low-frequency reinforcement in distributed outdoor systems.
What does each one require for installation?
The CBT 70JE-1 mounts vertically above or below the CBT 70J-1 base unit using shoulder eyebolts or swivel clips for suspension in indoor venues. The JBL-GSB12-TN requires an approximately 22-inch diameter, 26-inch-deep hole for permanent in-ground landscape burial.
