JBL CBT 70JE-1

No, this unit is specifically designed as an extension cabinet for the JBL CBT 70J-1 line array column. It is intended to be physically and electrically coupled with the main speaker to extend low-frequency response and improve pattern control.

The speaker comes with a coupling bracket system designed to securely attach it to the CBT 70J-1. You will need to ensure your mounting surface can support the combined weight of both units, which totals over 18 pounds for the extension alone.

Constant Beamwidth Technology ensures that the sound coverage remains consistent across a wide frequency range. This prevents the 'beaming' effect often found in standard speakers, resulting in more uniform audio clarity for listeners throughout the room.

Yes, the CBT 70JE-1 features a durable, fiberglass-reinforced ABS enclosure designed to withstand demanding environments. However, while the material is rugged, you should still ensure it is protected from direct, prolonged exposure to harsh elements if installed outdoors.

The CBT 70JE-1 is a passive extension that connects directly to the CBT 70J-1. It does not require a separate amplifier channel, as it is driven by the same signal path as the main column speaker when properly coupled.

Adding the 70JE-1 significantly extends the bass response down to 45 Hz and increases the vertical pattern control. This is particularly useful in large spaces where you need more low-end presence and tighter sound projection to maintain intelligibility.
