dV-SUB - High-Power dV-DOSC LF Extension

Inspired by the legendary V-DOSC®, dV-DOSC has set a reference in line source technology for both the fixed installation and rental production markets. The modular package features the dV-DOSC lightweight and compact enclosure derived from the HF/MF V-DOSC® section, and the complementary dV-SUB high power, compact 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
is desired.
