dV-SUB - High-Power dV-DOSC LF Extension As a standalone system, dV-DOSC complies with rigging and visual limitations in theatres, concert halls, convention centers and sport facilities. dV-DOSC delivers a flat contour, clarity, precision and intelligibility for vocal material and lead instruments with a unique near-field perception, offering an incomparable listening experience. When combined with dV-SUB, dV-DOSC delivers an extended bandwidth with a significant low-end impact and a sonic signature similar to the larger format WST® systems. dV-DOSC can also be implemented as a downfill system for V-DOSC® and K1 with a horizontal directivity of 120° adapted to coverage of the front audience. Its new LA8 preset library makes it entirely compatible and offers seamless sonic integration with both systems. |

L-ACOUSTICS® pioneered the field of modern line source array as early as 1993 with the introduction of Wavefront Sculpture Technology on the legendary V-DOSC® system. Based on physical rules developed by Heil and Urban (AES 1992) the WST® theory defines five criteria for design and use of true line source arrays. At the heart of Wavefront Sculpture Technology is the internationally-patented DOSC® waveguide, which morphs the spherical wavefront of the HF driver into a cylindrical, isophasic wave In combination with WST®, coplanar symmetry - the equivalent of coaxial assembly for HF, MF and LF drivers in vertical arrays - provides a coherent wavefront over the entire horizontal coverage at all frequencies. This behaves as if the sound was radiated by a single, continuous and articulated ribbon. |

Any line source featuring L-ACOUSTICS® elements respects the coplanar symmetry and all WST® criteria on the entire sonic spectrum. This allows an exceptionally coherent sonic signature in very long throw applications, beyond the limits of other systems. L-ACOUSTICS® has been designing reference line array systems for more than 15 years. Modular line sources offer tremendous flexibility for both the installation market and rental applications. Both KIVA and dV-DOSC systems are designed with the combination of a compact, high-performance and lightweight enclosure with a dedicated companion LF extension (KILO, dV-SUB) bringing the necessary LF resources when a large format system reinforced contour |

"We needed a PA system with outstanding vocal intelligibility and lots of headroom, our new dV-DOSC and dV-SUB arrays, augmented with the new SB28 subwoofers, provide all of that and more. The system delivers clear, perfect sound everywhere within the arena, with consistent, even coverage". | ![]() |

"Even if you’re standing right up by the dV-SUB in the balcony, you still get a very clear sound in the high-end as well". | ![]() |

"I am very happy with the dV-SUB. When associated with dV-DOSC it gives deeper impact than the V-DOSC system for mid-sized venues. Before we used dV-DOSC with SB218, but something was missing, a small gap between low bass and the mid-range which affected the impact”. He adds “now the dV-SUB really pushes the low energy into your body". |
