Dual 18" Subwoofer - Upphängbar

VTX-serien dual 18" subwoofrar använder två 2269H 18" transdusörer med Differential Drive-teknologi med två voice coils, två neodymmagneter och extremt höga peak-to-peak-rörelseegenskaper för att leverera utökad mycket låg frekvensöverföring.

VTX S28 kan upphängas eller stackas på marken och är cardioid-arraybar i båda konfigurationerna för förbättrad bakre eliminering. Kompatibel med VTX V25-upphängning kan S28 upphängas i toppen av V25-arrayer för att förlänga den effektiva lågfrekvenslinjelängden, vilket ger förbättrad vertikal mönsterkontroll tillsammans med förbättrad bakre eliminering när den används i cardioid-läge.

Alternativt kan S28-arrayer (cardioid eller framåtriktade) upphängas bredvid eller bakom V25-arrayer. För teatralisk ljuddesign kan S28 upphängas i mitten av upphängda V25-arrayer för att möjliggöra täckning av balkong och golv genom att tillåta förbättrad penetration under baldakinen. Större cardioid-konfigurationer är också effektiva där S28 är upphängd eller stackad på marken i flera cardioid-block, där varje block består av 3 höljen (2 framåtriktade, 1 bakåtriktad).

Single or dual extension bars can also be front- or rear-mounted in ground stack applications for extra stability and a wider range of array tilt angle options. Dual extension bars can also be front-and rear-mounted for compression suspension when increased array up-tilt is required.
