Dubbel 18" subwoofer – upphängningsbar

VTX-seriens subwoofers med dubbla 18"-element använder två 2269H 18"-transduktorer med Differential Drive-teknik, två talspolar, två neodymmagneter och extremt hög topp-till-topp-slaglängd för att leverera utökad återgivning av mycket låga frekvenser.

VTX S28 kan hängas upp eller markstackas och kan i båda konfigurationerna byggas i kardioidarray för förbättrad bakåtdämpning. S28 är kompatibel med VTX V25-upphängning och kan hängas upp i toppen av V25-arrayer för att förlänga den effektiva lågfrekvenslinjens längd, vilket ger förbättrad vertikal spridningskontroll i kombination med förbättrad bakåtdämpning vid användning i kardioidläge.

Alternativt kan S28-arrayer (kardioid eller framåtriktade) hängas upp vid sidan av eller bakom V25-arrayer. För ljuddesign i teatermiljöer kan S28 hängas upp i mitten av upphängda V25-arrayer för att underlätta täckning av balkong och golv genom förbättrad penetration under balkongen. Större kardioidkonfigurationer är också effektiva när S28 hängs upp eller markstackas i flera kardioidblock, där varje block består av 3 kabinett (2 framåtriktade, 1 bakåtriktat).

DIFFERENTIAL DRIVE® TECHNOLOGY

Förbättrad prestanda och dramatiskt lägre vikt på drivenheterna

JBL:s exklusiva Differential Drive-teknik med dubbla talspolar och dubbla magnetspalter utgör kärnan i samtliga VTX-modeller. Den minskar drivenheternas vikt dramatiskt och förbättrar samtidigt alla kritiska prestandaparametrar avsevärt: frekvensåtergivning, uteffekt och distorsion.
