Constant Beamwidth Technology™ tvåvägs linjearray-kolumn med asymmetrisk vertikal täckning. Med förbättrad monteringsclips för ökad inriktningsflexibilitet och starkare galler.

CBT 70J-1, med Constant Beamwidth Technology™, representerar ett genombrott inom mönsterkontrollkonsistens genom att använda komplex analog fördröjningsstrålformning och amplitudtapering för att uppnå överlägsen, konsistent vertikal täckning utan den smala vertikala strålning och utanför-täcningen lobing som är typisk för raka linjearray-högtalarkolumner. (visas med medfölјande galler borttaget)

Funktioner

Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent.
Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers,
arranged coaxially.
Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
Vertical pattern coverage switchable between 45° for medium-throw coverage and 25° for
long-throw applications.
Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
Dynamic SonicGuard™ overload protection of HF devices
Swivel (pan) / tilt wall bracket included.
