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 20 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, 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.
