JBL CBT 70J-1-WH - 500W 4 x 5-inch Passive 2-Way IP55-Rated Column Loudspeaker with 150 x 25/45-Degree Coverage in White Finish

The JBL Professional CBT 70J-1-WH is an advanced, high-performance passive column loudspeaker designed to provide superior sound quality, consistent vertical coverage, and excellent pattern control. Utilizing JBL's patent-pending Constant Beamwidth Technology (CBT), the CBT 70J-1-WH eliminates the common issues of narrow vertical beaming and out-of-coverage lobing found in traditional column speakers. The speaker's unique J-shaped curving creates asymmetrical vertical coverage, which produces a tighter concentration of sound in the upper half of the array, directing more sound to the far areas of the room. This results in a more even front-to-back SPL (sound pressure level), ensuring consistent coverage throughout the listening area, particularly in large, acoustically challenging spaces.

With a frequency range of 60 Hz to 20 kHz and a broad 150° horizontal coverage, the CBT 70J-1-WH delivers clear, intelligible sound over long distances, making it perfect for applications such as lecture halls, auditoriums, transit centers, racetracks, theme parks, stadiums, and multipurpose spaces. The speaker's slim design - measuring 27.4 inches tall and 6.7 inches wide - allows it to blend seamlessly into virtually any architectural setting. It is an ideal solution for venues that require high-quality, wide-range sound with exceptional pattern control, particularly when mounted in challenging acoustic environments.

The CBT 70J-1-WH is engineered with versatility in mind. The vertical coverage can be switched between two modes: a narrow 25° pattern for long-throw applications and a broad 45° pattern for medium-throw coverage. The speaker can also be set to an asymmetrical progressive-gradient mode, which combines narrow coverage from the top module and broad coverage from the bottom module, making it an excellent choice for applications that require coverage adjustments from front to back in large venues. The voicing can be easily tailored for different environments using the Music/Speech switch. The Music mode offers flat frequency response, while the Speech mode boosts mid-range frequencies to enhance speech intelligibility at longer distances.

Built with durability and longevity in mind, the CBT 70J-1-WH features weather-resistant drivers and a fiberglass reinforced ABS cabinet. The cabinet is coated with UV-resistant paint, making it suitable for both indoor and outdoor use. The heavy-duty aluminum grille ensures long-lasting performance in outdoor environments, providing rust-free protection in harsh weather conditions. The speaker is also IP-55 rated when used with the optional MTC-PC2 terminal panel cover, which offers additional protection against UV rays, moisture, and salt-spray exposure.

The low-frequency drivers in the CBT 70J-1-WH are high-performance 5-inch drivers with dual neodymium magnets and 1.5-inch voice coils, providing high power handling and minimal distortion. The high-frequency drivers are soft dome tweeters designed with neodymium motors to ensure maximum sensitivity and performance. Both the LF and HF drivers are magnetically shielded to prevent interference from nearby CRT monitors, making this speaker ideal for environments where close placement of displays is required. The combination of dynamic SonicGuard overload protection, high-power handling, and weather-resistant construction makes the CBT 70J-1-WH an outstanding choice for a wide range of installations.

The CBT 70J-1-WH is designed for easy installation. It comes with a swivel (pan) / tilt wall-mount bracket, allowing for flexible left-right swivel and tilt adjustment. With ten threaded M6 insert points, the speaker can also be suspended using forged shoulder steel eyebolts or compatible third-party mounting brackets. The speaker's versatility extends to its transformer taps, which support both 70V and 100V configurations, making it compatible with various distributed audio systems. The CBT 70J-1-WH also supports an 8-ohm direct connection for traditional systems. The speaker is available in both black and white finishes, allowing it to blend seamlessly into various architectural styles.

The JBL Professional CBT 70J-1-WH offers outstanding sound quality, reliable durability, and flexible installation options, making it a top choice for applications where superior coverage and intelligibility are paramount.
