L-ACOUSTICS KUDO designed for both planes
Vertical and Horizontal
Abstract
The working concept of the new LACOUSTICS KUDO line source array began with the goal of offering a higher degree of flexibility. Specifically, we were seeking to offer our patented Wavefront Sculpture Technology (WST) in both vertical and horizontal planes, and further, to make this coverage adjustable to fit a wide range of applications.

KUDO Specifications
KUDO Spec Sheet
Abstract
L-ACOUSTICS®KUDO is a new generation of line source array offering far more flexibility and possibilities than any other line array to date. KUDO marks a significant evolution in L-ACOUSTICS pioneering Wavefront Sculpture Technology®(WST) since WST can now be performed in both vertical and horizontal planes simultaneously.

KUDO Technical Description
Abstract
When used as a vertical line source array, L-ACOUSTICS KUDO offers inter-enclosure
angular spacing between 0° to 10° with increments of 1° while fully respecting all WST
conditions. With maximum angling between enclosures, constant vertical directivity of 60°
can be obtained using six L-ACOUSTICS KUDO. For longer throw applications, inter-
enclosure angular spacing can be adapted to the audience geometry in accordance with WST
condition 4 to provide the equivalent of cylindrical wavefront propagation and optimize SPL
distribution and tonal balance over the desired coverage area.

Line Array Q&A – V2
Question: Why Line Arrays?
Abstract
First, what’s the goal with any quality sound system? To provide well-defined, full-frequency
coverage as consistently as possible from seat to seat. However, traditional speaker cluster
approaches have been inherently limited in their ability to address this goal because of interference
created by the interaction between the cabinets.

The Distributed Edge Dipole (DED) Model
AES Journal 2004
Abstract
A simple model is proposed to account for the effects of cabinet edge diffraction on the
radiated sound field for direct-radiating loudspeaker components when mounted in an en-
closure. The proposed approach is termed the distributed edge dipole (DED) model since it
is developed based on the Kirchhoff approximation using distributed dipoles with their axes
perpendicular to the baffle edge as the elementary diffractive sources. The DED model is first
tested against measurements for a thin circular baffle and then applied to a real-world
loudspeaker that has a thick, rectangular baffle. The forward sound pressure level and the
entire angular domain are investigated, and predictions of the DED model show good agree-
ment with experimental measurements

Line Arrays Versus Line Source Arrays
About L-ACOUSTICS Technology
Abstract
There is a big difference between a line source array and a line array. We hope to elaborate on this
throughout the course of this article following an analysis of the limitations of conventional horn-loaded
systems and a description of the technology behind V-DOSC®, dV-DOSC® and ARCS® that we term
Wavefront Sculpture Technology® (WST®).

Wavefront Sculpture Technology, October 2003
AES Journal, Vol. 51, #10
Abstract
The Fresnel approach in optics is introduced to the field of acoustics. Fresnel analysis provides an effective, intuitive way of understanding complex interference phenomena and allows for the definition of criteria required to couple discrete sound sources effectively and to achieve coverage of a given audience geometry in sound-reinforcement applications. The derived criteria from the basis of what is termed Wavefront Sculpture Technology.

Wavefront Sculpture Technology
AES Convention Paper #5488
Article presented at the 111th AES Convention, New York 2001
Abstract
We introduce Fresnel’s ideas in optics to the field of acoustics. Fresnel analysis provides an effective, intuitive approach to the understanding of complex interference phenomena and thus opens the road to establishing the criteria for the effective coupling of sound sources and for the coverage of a given audience geometry in sound reinforcement applications. The derived criteria form the basis of what is termed Wavefront Sculpture Technology.
