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. Features: Components: Six (6) 165 mm (6.5 in) high-excursion LF drivers (CBT1000E) 1500 Watt power handling (CBT1000E) Built-in purpose-designed crossover network, for combining with CBT1000 (CBT1000E) Coupler plate included (CBT1000E) Extended pattern control Components: 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) 3000 watt power handling (CBT1000+1000E) Patent-pending 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 (CBT1000) 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 (CBT1000) Single-speaker system room coverage at high SPL, with little over-splash and strong bass response down to below 38 Hz (CBT1000+1000E) Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode (CBT1000) Swivel (pan)/tilt wall bracket and coupler plate included. 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) Frequency Range: (-10dB) 38 Hz - 20 kHz Coverage: Vertical (selectable via switch) 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 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.
