Constant Beamwidth Technology ? Adjustable Coverage Line Array Column with Asymmetrical Vertical Coverage and Tapered Horizontal Coverage
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.
FEATURES
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.

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°
