JBL Professional CBT 1000E High Output Column Extension Speaker, White

Extend the reach and impact of your CBT1000 line array with the JBL Professional CBT 1000E column extension speaker. Designed to give installers and system designers greater low-frequency output and more consistent pattern control, this extension delivers the extra SPL and bass needed for large auditoriums, transit hubs, outdoor venues and critical security paging. When paired with a CBT1000, the CBT 1000E leverages JBL's Constant Beamwidth Technology to maintain uniform vertical coverage while minimizing lobing and off-axis nulls — improving speech intelligibility for monitoring, surveillance and live events.

Built for professional installations, the CBT 1000E provides 1500W RMS power handling and a frequency range down to 38 Hz with up to 130 dB sensitivity, giving you the headroom and punch required for demanding applications. The included coupler plate and purpose-designed crossover make system integration seamless, while the white, wall-mountable enclosure blends into architectural installs. Ideal for auditoriums, houses of worship, sports venues and security/monitoring systems — add the CBT 1000E to your CBT1000 array to expand coverage and order or contact sales for a site consultation.
