Constant Beamwidth Technology™ toveis linjearray-søjle med asymmetrisk vertikal dækning. Med forbedret monteringsbøjle for øget sigtningsfleksibilitet og stærkere gitter.

CBT 70J-1 med Constant Beamwidth Technology™ repræsenterer et gennembrud inden for konsistens af mønsterkontrol ved hjælp af kompleks analog forsinkelsesstrålekonfiguration og amplitudtapering for at opnå overlegen, konsistent vertikal dækning uden den snævre vertikale stråling og out-of-coverage-lobe, som er typiske for søjlehøjttalere med lige form. (vist med medfølgende gitter fjernet)

Funktioner

Asymmetrisk vertikal dækning sender mere lyd mod baggrund af rummet for at gøre lydniveauerne fra front til baggrund mere konsistente.
Komponenter: Seksten 25 mm (1 tomme) bløde kuppeltweetere og fire 125 mm (5 tomme) højeffekt-LF-drivere,
arrangeret koaksialt.
Patent-afventende Constant Beamwidth Technology™ giver konstant retningskarakteristik op til de højeste frekvenser og reducerer ud-af-dækning lobing.
Vertikal mønsterdækning kan skiftes mellem 45° for medium-afstands dækning og 25° for
langkastningsapplikationer.
Skiftbar stemning giver flad respons i musikmode eller midrække-nærvær peak i taletilstand.
Dynamisk SonicGuard™ overbelastningsbeskyttelse af HF-enheder
Svingbar (pan) / vip-vægbeslag inkluderet.
