The L-ACOUSTICS® dV-SUB is the companion subwoofer for dV-DOSCTM and features three 15-inch transducers loaded in a dual-chamber vented bandpass configuration. With power handling capacity of 1200 Wrms and response to 35 Hz, dV-SUB is ideal for applications requiring maximum low end impact from an extremely compact enclosure. Important design criteria in the development of dV-SUB were maximum SPL output combined with low frequency extension from an enclosure as compact as possible. Dual-chamber vented bandpass loading provided the answer. High power handling components also contribute to the SPL performance and since 15” transducers are operated in parallel this presents an optimum 2.7 ohm load to the power amplifier. Rigging flexibility was another key consideration and dV-SUB’s integral rigging system allows for the installation of a single flown column of dV-DOSC and dV-SUB enclosures (with dV-SUB flown at the top of the array and dV-DOSC underneath). Although deeper than dV-DOSC, dV-SUB has the same width and in keeping with the recommended ratio of 3 dV-DOSC : 1 dV-SUB, enclosure height is equivalent to approximately 3 dV-DOSC. This allows for the creation of physically compact arrays when dV-SUB is flown on either side of dV-DOSC in a coplanar symmetric arrangement. Either single column or coplanar symmetric flown configurations can be used in FOH applications for small, medium or large venues and also in large-scale fixed installations such as multiple distributed arrays for stadium or arena sound reinforcement. For theatrical applications, where visually unobtrusive sound design is critical, dV-DOSC plus dV-SUB is ideal for stereo infill (floor), main left/right (balcony) or center cluster use. The 695 mm (27.4-in) cubic dimensions of dV-SUB are highly convenient for ground-stacked applications where dV-SUB serves as a stacking platform for dV-DOSC.This combination is also ideal for stage monitoring applications such as sidefill or drum fill. Presets for use of dV-SUB with the L-ACOUSTICS XT line, 115FM floor monitor and ARCS are also available, offering a wide variety of enclosure combinations.
