The CBT1000 Two-Way Line Array Column Loudspeaker from JBL 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. Utilizing complex analog beam-forming, the speaker provides consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing.
JBL CBT 1000 Features
- Available in black (pictured) or white (not pictured)
- Asymmetrical vertical coverage sends more sound toward far area of 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.
- 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.
- Single-speaker room coverage at high SPL, with little over-splash and strong bass response down to below 40 Hz.
- Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
- Swivel (pan)/tilt wall bracket included.

- 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
- Vertical Coverage Settings Coverage is effective (frequency response similar) beyond the traditional -6 dB coverage angles. This is especially useful in compensating for differences in listening distances. Figures show both the -6 dB and -12 dB coverage angles (at 3 kHz). Angles are in reference to cabinet aiming axis. Pattern UP Settings: “Point”: -6dB @ +7°, -12 dB @ +12° “Tight”: -6dB @ +9°, -12 dB @ +15° “Narrow”: -6dB @ +10°, -12 dB @ +20° “Medium”: -6dB @ +13°, -12 dB @ +24° Pattern DOWN Settings: “Point”: -6dB @ -7°, -12 dB @ -12° “Narrow”: -6dB @ -10°, -12 dB @ -20° “Broad”: -6dB @ -17°, -12 dB @ -28° “Downfill”: -6dB @ -20°, -12 dB @ -35°
- Horizontal Coverage -pending Tapered Horizontal Waveguide continuously variable. Long-throw (top) section: 100° Middle section: 130° Short-throw (bottom) section: 160°
- Recommended High-Pass 35Hz, 24 dB/oct or greater
- Low Frequency Drivers 6 pcs, 165 mm (6.5 in) drivers, lightweight neodymium motors, 50 mm (2.0 in) diameter voice coils, copper-capped pole tips to minimize flux modulation and linearize inductance, 16 mm (0.63 in) long coil for high linear drive and high power handling, damped blended textile surround, coated cones for moisture, UV and salt resistance. Magnetically shielded.
