Features

Overview: The JBL CBT 70JE-1 line array column speaker extension represents the latest generation of pattern-controlled speakers, providing consistent listening-space coverage, superior sound quality, and versatility for a wide variety of applications. The CBT 70JE-1 is designed to work as an "extension" of the JBL CBT 70J-1 line array column speaker (sold separately), providing extended bass response, extended pattern control, and increased sound output levels. The CBT 70J-1 + 70JE-1 combination is an ideal solution for performance auditoriums, houses of worship, lecture halls, cinema main speakers or very high-output surrounds, transit facilities, theme parks, and more. The JBL column speaker can be used outdoors as well.

Drivers: The JBL CBT 70JE-1 column speaker extension houses four 5" high-excursion woofers arranged in a vertical fashion. Each of the four low-frequency drivers is comprised of a coated, sealed paper cone with blended textile surrounds. They feature lightweight neodymium motors with 1.5" voice coils, providing maximum flux, and are magnetically shielded. Copper caps on the pole-piece minimize flux modulation and linear inductance, resulting in lower distortion and improved frequency response.

Constant Beamwidth: Incorporating JBL's Constant Beamwidth Technology, the line array column speaker extension utilizes analog delay beam-forming and amplitude tapering to provide consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical in straight column speakers.

Outdoor Use: The CBT 70JE-1 is designed to be installed either indoors or outdoors. The enclosure is made from fiberglass reinforced ABS, coated with UV resistant paint, and includes a powder-coated 1050 aluminum grille. All drivers are weather-treated for protection from moisture, UV rays, and salt spray. An optional MTC-PC2 panel cover (sold separately) can seal the terminal compartment from excessive moisture, giving the line array column speaker an IP55 rating.

Mounting: The JBL CBT 70JE-1 line array column speaker extension includes a coupler plate for attaching it to the top section of a CBT 70J-1 line array column speaker. A two part wall-bracket is also included that can provide ±45° of swivel and ±15° of tilt. Ten M6 threaded brass inserts along the back panel offer a wide variety of spacing patterns for the included brackets, as well as common third-party mounting brackets. The threaded mounting points can also be used for suspending the speaker (hardware not included).
