JBL CBT 1000E-WH Extension for CBT1000 Line Array Passive Column Loudspeaker

When connected to a CBT1000 line array column speaker, the CBT1000E Extension provides extended bass response, extended pattern control, and increased sound output levels. The combined array system provides Constant Beamwidth Technology™, which represents a breakthrough in pattern control consistency, utilizing complex analog beamforming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of passive column speakers.

Specifications:

Drivers: Twenty-four (24) 25 mm (1 in) extra-high-power soft dome tweeters and Twelve (12) 165 mm (6.5 in) high-excursion LF drivers (CBT1000+1000E)

Impedance: 4 ohms

Power Rating: 3000 W (12000 W peak), 2 hrs2000 W (8000 W peak), 100 hrs

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 Highest directivity setting: (“Point” pattern up, “Point” pattern down) with “Music” voicing:      127 dB continuous average pink noise      130 dB continuous program      133 dB peak Lowest directivity setting: (“Medium” pattern up, “Downfill” pattern down) with “Speech” voicing:      128 dB continuous average pink noise      131 dB continuous program      134 dB peak Lowest directivity setting: (“Medium” pattern up, “Downfill” pattern down) with “Music” voicing:      124

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°          

Horizontal Coverage: Patent-pending Tapered Horizontal Waveguide continuously variable.      Long-throw (top) section: 100°      Middle section: 130°      Short-throw (bottom) section: 160°

Low Frequency Drivers: 12 pcs, 165 mm (6.5 in) drivers, neodymium, 50 mm (2 in) voice coil, damped blended textile surround, coated diaphragm for moisture, UV, and salt resistance.

High Frequency Drivers: 24 pcs, 25 mm (1 in) drivers, neodymium, encased magnet and coated diaphragm for moisture, UV, and salt resistance.
