CBT 1000 Constant Beamwidth Technology™ High-Output Two-Way Line Array Column with Adjustable Vertical Coverage & Tapered Horizontal Waveguide Key Features: u V ertical pattern coverage individually adjustable with four (4) “Pattern Up” coverage angles and four (4) “Pattern Down” coverage angles for a total of sixteen (16) different coverage combinations, all without the use of external DSP processing. u Asymmetrical vertical settings send more sound toward far area of room to make front-to-back sound levels more consistent. u Components: • T wenty-four (24) 25 mm (1 in) extra-highpower soft dome tweeters. • S ix (6) 165 mm (6-1/2 in) high-excursion LF drivers arranged coaxially. u Very high sound levels up to 131 dB (137 dB peaks), depending on the settings. u Constant Beamwidth Technology™ provides constant directivity coverage and reduces out of coverage lobing. u Patent-pending Tapered Horizontal Waveguide provides a continuously varying horizontal dispersion (very wide for short-throw, narrower for long-throw) delivering superior coverage in both the front and rear corners of a room and reducing over-splash. u Wide 45 Hz - 20 kHz frequency response. u Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode. u Swivel (pan)/tilt wall bracket included. Shown with included grille. Grille removed. Overview: The CBT 1000 represents the next-generation in pattern control, expanding upon JBL’s highly successful CBT Constant Beamwidth Technology™ products. Utilizing patented complex analog beam-forming, the CBT 1000 provides superior and consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers. The CBT 1000 combines Constant Beamwidth Technology with adjustable vertical coverage and a tapered horizontal waveguide to increase the versatility of aiming the coverage of the loudspeaker to more accurately map to the room geometry in a wide variety of listening spaces. The asymmetrical coverage settings produce a higher concentration of sound with a tighter pattern from the upper half of the array, and a lower concentration of sound with a broader vertical pattern from the lower half of the array. This sends more sound toward the far area of the room than to the near area of the room, resulting in more even front-toback SPL levels than would be the case from a traditional speaker or column that projects symmetrically in the vertical plane. Additionally, the vertical coverage pattern is individually installer adjustable though a range of four “Pattern Up” coverage angles and four “Pattern Down” coverage angles for a total of sixteen different coverage combinations, all without the use of any external DSP processing. The new patent-pending Tapered Horizontal Waveguide design provides a continuously varying horizontal dispersion by providing a very wide angle of dispersion for the short-throw distances while also providing a narrower horizontal angle of dispersion for the long-throw distances, providing superior coverage in both the front and rear corners of a room. The consistent pattern control allows the CBT 1000 to work well in difficult acoustic environments. The two-way coaxial design provides a wide 45 Hz – 20 kHz bandwidth. The low-diffraction baffle eliminates frequency response irregularities that could otherwise occur due to baffle discontinuities. The thick, heavy-duty aluminum grille allows for rust-free installation outdoors. At 102 cm (40.2 in) tall and only 25 cm (9.9 in) wide, the design fits well with virtually any architectural décor. CBT 1000 Two-Way Line Array Column with Adjustable Vertical Coverage and Tapered Horizontal Waveguide Applications Combining superior sound quality, excellent pattern control, asymmetrical vertical coverage, continuously variable horizontal dispersion, and compact design makes the CBT 1000 extremely versatile. It is ideal for applications such as performance auditoriums, houses of worship, lecture halls, classrooms, cinema main speakers or very high-output surrounds, multipurpose spaces, A /V, transit centers, sports facilities, racetracks, theme parks, outdoor locations, and high-level fill applications, among many others. Adjustable Coverage to Fit the Application Vertical pattern coverage settings are set via easy-to-configure headers located in a covered compartment on the side of the speaker. The innovative adjustability allows the installer to switch through a range of four (4) “Pattern Up” coverage angles and four (4) “Pattern Down” coverage angles for a total of sixteen (16) different coverage combinations. Additionally, the use of a patent-pending Tapered Horizontal Waveguide provides a continuously varying horizontal dispersion (very wide for short-throw, narrower for mid-throw, even more narrow for long-throw) delivering superior coverage in both the front and rear corners of a room while reducing undesirable over-splash. These unique features allow the user to more closely match the coverage and throw requirements to the application, and the coverage selection can be easily switched in-venue with the speaker already installed. These innovations allow a single loudspeaker model to excel in an extremely wide variety of project types. User Variable Voicing The voicing can be set to match the application through a Music/Speech switch. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances, along with increased midrange sensitivities for higher midrange maximum output capability. Drivers The low frequency drivers feature lightweight neodymium motors with 50 mm (2.0 in) diameter voice coils. The magnet system provides maximum flux in a compact package. The magnet structure is magnetically shielded and the drivers have a copper cap on the pole to minimize flux modulation and linearize inductance, resulting in lower distortion and improved frequency response. The 16 mm (0.63 in) long coil provides high linear drive and high power handling in a compact driver. The LF drivers feature damped blended textile surrounds and coated sealed paper cones found in high performance large format drivers. The high frequency drivers include neodymium structure for maximum sensitivity, and feature high power handling, long excursion and large back enclosures for additional frequency range and output. The tweeter is encased for weather resistance. Both drivers feature coated diaphragm materials to provide moisture, UV and salt resistance for outdoor capability. SonicGuard™ Dynamic SonicGuard™ protection on the high frequency section minimizes distortion at high drive levels by limiting driver excursion dynamically. This maximizes music clarity and speech intelligibility at high drive levels while protecting the drivers from damage due to occasional overpowering. Bracketry & Insert Points A two-part swivel (pan) / tilt wall-mount bracket is included. Fourteen (14) M8 brass inserts are located on the back panel in a spacing pattern that fits common third-party mounting brackets. In addition, four insert points each are located on the top and bottom end-caps. These insert points can be utilized to suspend the speaker using forged shoulder steel eyebolts or swivel mounting rings, providing installation versatility. Optional brackets include MTC-CBT-FM3 (in MTC-CBT1K-ACC1 kit) for flush-mounting the back of the speaker to a wall, and MTC-CBT-SUS3 CBT Series suspension bracket kit. Outdoor Capability CBT 1000 can be installed either indoors or outdoors. The drivers are weather-treated, the fiberglass reinforced ABS cabinet is excellent for outdoor applications, and the paint is UV resistant. External screws are stainless steel and the powder coated 1050 aluminum grille resists rust in the harshest of conditions. The optional MTC-PC2 panel cover with gland nut seals the terminal compartment from excessive moisture. Color Available in black (RAL9004) or White (-WH) (RAL9016).
