WST® Technology - Variable Curvature

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.

 


Variable curvature, modular (KIVA and KARA)

Modular line sources offer tremendous flexibility for both the installation market and rental applications. Both KIVA and KARA® systems are designed to combine a compact, high performance and lightweight enclosure with a dedicated companion LF extension (KILO, SB15m, SB18) delivering the necessary LF resources when a reinforced contour is desired.

Variable curvature, large format (KUDO, V-DOSC and K1)

These systems are particularly suited to large format installations and touring applications for which a reinforced LF contour is desirable. 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 Network Manager deliver a “right out of the box” contour adjustable with Array Morphing to obtain an homogeneous signature in complex system configurations.

 "L-ACOUSTICS' dV-DOSC has always been one of my favorite loudspeakers, especially for theatre because the vocal quality is so wonderful. But I have to say that the essence of dV-DOSC--and now KARA--translates down very well into the much smaller and more cost-effective KIVA enclosures. They possess the same clarity and truth of reproduction, particularly in the vocal bandwidth, and really sound fantastic in these relatively intimate spaces."

 "We found that KIVA was sonically superior and its weight and form factor are ideal for our primary market of conferences."

“My initial impression of the KIVA-KILO system was simply ‘wow’. I was extremely impressed, both with what I saw and heard. The arrays are small, compact, and lightweight enough to hang from the hall’s cantilevers as a single-point hang. One of my bosses commented on how sexy he thought these curvy cabinets looked, and it’s true that they are very visually appealing, but their audio far exceeds their visual appeal.”
