The JBL CBT1000E extension for the CBT1000 line array column speaker extends bass response, pattern control, and sound output. From the Manufacturer: 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.
