The JBL is an Adjustable Coverage Column Installation Speaker. Expanding upon our highly successful Constant Beamwidth Technology breakthrough, the CBT1000 represents the next generation in pattern control consistency utilizing 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. Asymmetrical vertical coverage sends more sound toward the far area of the room to make front-to-back sound levels more consistent. Components Twenty-four (24) 25 mm (1 in) extra-high-power soft dome tweeters and six (6) 165 mm (6-1/2”) high-excursion LF drivers arranged coaxially. Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. Vertical pattern coverage is individually adjustable through a range of four (4) “Pattern Up” 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. Product Specifications: Drivers: Six (6) 165 mm (6.5 in) LF drivers Twenty-four (24) 25 mm (1 in) HF drivers Frequency Range (-10dB): 45 Hz – 20 kHz Sensitivity: 102 dB (at highest sensitivity setting: “Point” pattern up, “Point” pattern down, “Speech” voicing, in free space); 95 dB (at lowest sensitivity setting: “Medium” pattern up,“Downfill” pattern down, “Music” voicing in free space) Impedance: 4 ohms (4 ohms above 1 kHz; 8 ohms below 800 Hz) Power Rating: 1500 W (6000 W peak), 2 hrs; 1000 W (4000 W peak), 100 hrs Maximum Input Voltage: 65.0 Volts RMS (2 hrs), 130.0 Volts Peak Maximum SPL (1m): Highest directivity setting: (“Point” pattern up, “Point” pattern down) with “Speech” voicing: 131 dB continuous average pink noise, 134 dB continuous program, 137 dB Peak High-Frequency Drivers: 24 pcs, 25 mm (1 in) drivers, neodymium, encased magnet and coated diaphragm for moisture, UV, and salt resistance. Enclosure: Fiberglass reinforced ABS cabinet, powder-coated 1050 aluminum grille Outdoor Capability: IP-55 rated, per IEC529, when installed with optional MTC-PC2 cover.
