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.
The DOSC® Waveguide
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. The signal path through the waveguide permits the fulfillment of WST® criteria at high frequencies, allowing elements to couple coherently and create a single, continuous, isophasic sound source. The implementation of the DOSC® waveguide explains why L-ACOUSTICS® systems satisfy the WST® criteria at high frequencies, as opposed to other line arrays.
Variable curvature, modular line sources
Modular line sources offer maximized flexibility for installation and rental applications. KIVA or KARA®(i) enclosures can be arrayed as compact and lightweight variable curvature line source which can comply with rigging and architectural constraints, while preserving sightlines. A dedicated companion LF extension (KILO, SB15m, SB18(i)) delivers the necessary LF resources. The sub: main ratio can be adjusted to accommodate various LF contour requirements.
Variable curvature, large format line sources
(KUDO, V-DOSC, K2 and K1)
These true full range systems are particularly suited to large format installations and touring applications for which a native and coherent LF performance is required. The touring systems rely on the Rental Network K platform featuring the LA-RAK plug-and-play amplification, signal processing and signal distribution rack. The amplified controllers and LA NETWORK MANAGER deliver a “right out of the box” contour adjustable with array morphing to obtain an homogeneous signature in complex system configurations.
