JBL CBT 1000E-WH Purpose-Designed Extension Loudspeaker for CBT 1000 (White)

Product Overview

The JBL CBT 1000E-WH is a purpose-designed line array extension loudspeaker that pairs with the CBT 1000 column to extend low-frequency response, vertical pattern control, and output in demanding commercial installations. Built for houses of worship, auditoriums, and large multi-purpose rooms, this CBT 1000 bass extension adds six 6.5-inch high-excursion LF drivers below the main column. Together the CBT 1000 + 1000E system delivers Constant Beamwidth Technology coverage with strong low-frequency extension and high SPL from a single architectural column. The white finish supports clean integration on walls and structural columns.

Product Description

The CBT 1000E-WH is not a standalone loudspeaker; it is an extension module that mechanically and electrically couples to the CBT 1000 to form a taller, higher-output line array column. It contributes six 165 mm (6.5 in) high-excursion low-frequency drivers and a built-in, purpose-designed crossover network that integrates with the CBT 1000 to extend both bass response and vertical pattern control. When combined, the CBT 1000 + CBT 1000E system presents twenty-four 25 mm soft-dome tweeters and twelve 165 mm LF drivers, providing room-filling coverage with strong low end and reduced out-of-coverage lobing. This makes the pairing well suited to reverberant rooms where intelligibility and even coverage are priorities, such as worship spaces and auditoriums. The included coupler plate joins the extension to the main column, and the assembly mounts with the CBT 1000 swivel/tilt hardware for precise audience aiming. Integrators specifying column arrays for installed audio can source the full CBT family from our JBL Professional passive PA speakers collection. The CBT 1000E should always be specified alongside a CBT 1000 main column rather than used on its own.

Frequently Asked Questions

Can the CBT 1000E-WH be used on its own?
No. The CBT 1000E is a purpose-designed extension module that must be paired with a CBT 1000 main column; it relies on the combined-system crossover and coupler plate to function as part of the array.

What does the extension add to a CBT 1000 system?
It extends low-frequency response, increases vertical pattern control, and raises maximum output, turning the CBT 1000 into a taller, higher-SPL column suitable for larger reverberant rooms.

How does it mount to the main column?
An included coupler plate joins the extension to the CBT 1000, and the assembly uses the CBT 1000 swivel/tilt wall bracket for aiming and structural support.

Is it suitable for AV integration in worship and auditorium spaces?
Yes. The CBT 1000 + 1000E system is designed for high-intelligibility speech and program audio in reverberant commercial venues, and Creation Networks can assist with system and amplifier specification.
