JBL CBT 1000-WH - 1500W 6 x 6.5-inch Passive 2-Way IP55-Rated Column Loudspeaker with Adjustable Beam Coverage in White Finish

The JBL Professional CBT 1000-WH is a high-performance, passive 2-way column loudspeaker designed to provide superior pattern control and full-range sound reinforcement. This model, finished in white (RAL9016), builds upon JBL's acclaimed Constant Beamwidth Technology (CBT), offering enhanced coverage and acoustics for a variety of applications. The CBT 1000-WH is ideal for venues requiring precise sound distribution such as concert halls, large conference rooms, sports arenas, and theaters, offering a sleek and professional aesthetic that integrates seamlessly into most architectural environments.

Designed to deliver exceptional vertical coverage, the CBT 1000-WH uses advanced beam-forming technology to eliminate the narrow vertical beaming and lobing often associated with traditional column speakers. With 24 high-power 25 mm (1 in) soft dome tweeters and six 165 mm (6.5 in) high-excursion low-frequency drivers, the CBT 1000-WH offers a powerful combination of broad coverage and high output. The coaxial arrangement of the drivers ensures uniform sound distribution, while the low-diffraction baffle enhances frequency response consistency, reducing irregularities commonly found in other designs. With its integrated tapered horizontal waveguide, the CBT 1000-WH provides superior horizontal dispersion, offering a wide angle of coverage for short-throw applications and a narrower dispersion for long-throw distances, which optimizes sound performance across a wide range of listening spaces.

One of the standout features of the CBT 1000-WH is its adjustable vertical pattern control. The system offers four distinct "Pattern Up" angles and four "Pattern Down" angles, providing up to sixteen different vertical coverage settings without requiring external DSP processing. This flexibility allows installers to tailor the coverage to the acoustics of the room, ensuring consistent sound levels throughout the venue. The system's asymmetrical vertical coverage settings project more sound toward the far areas of the listening space, helping to maintain consistent front-to-back SPL levels, making it particularly effective in rooms with varying distances between the speaker and audience.

The CBT 1000-WH also includes a switchable voicing feature, which allows the user to select between a flat response for music applications or a mid-range presence peak for speech, enhancing clarity and intelligibility. This ensures the system can adapt to a wide range of sound reinforcement needs. With a frequency range of 55 Hz - 20 kHz and a maximum SPL of 137 dB peak, the CBT 1000-WH delivers powerful, clear sound even at high output levels. The enclosure is built from durable ABS with a fiberglass-reinforced baffle, and the 1050 aluminum grille is rust-resistant, making the speaker suitable for both indoor and outdoor environments, with an IP55 rating for weather resistance.

The CBT 1000-WH is equipped with a removable locking 4-pin connector for secure, easy wiring, and the system includes a swivel (pan)/tilt wall bracket for precise installation. The speaker's design allows for continuous variable left-right swivel aiming without up/down tilt, giving the installer flexibility in achieving the desired coverage. The cabinet's slim profile (40.2 inches tall and 9.9 inches wide) makes it ideal for mounting in a variety of locations, ensuring that it fits with virtually any decor. Additionally, the system is compatible with the optional MTC-CBT-SUS3 suspension bracket kit, which allows for ceiling suspension, and the MTC-CBT1K-ACC1 accessory kit provides additional mounting flexibility.
