从建立之初，L-ACOUSTICS就坚持不断创新和采用科学的方法的宗旨。L-ACOUSTICS最初植根于在物理和基础声学方面，L-ACOUSTICS被誉为现代线声源阵列的鼻祖，这归功于它发明的波阵面纠正技术（Wavefront Sculpture Technology）和传奇性的V-DOSC系统。
　然而随着时间的推移，L-ACOUSTICS已经把它的研究活动拓展到结构工程，动力电子技术，信号处理和数字网络领域。L-ACOUSTICS还研发了自己内部的模拟建模工具，并通过大量的实验以验证模型的正确性。此外，L-ACOUSTICS经常在科学界发布所取得的研究成果。作为一个工程技术推动型的团队，L-ACOUSTICS是音频制造行业最受尊敬的组织之一。

 ARCS FOCUS 箱体的标称工作频率带宽达到55Hz—20kHz，与SB18m 超低频扬声器同时使用时，频率可扩展至32Hz。DOSC 高频波导产生15°×90°对称的指向性。
 耦合棒允许ARCS FOCUS 以恒定的曲率水平或垂直排列，在高频部分的DOSC波导管，在没有打破内在元素的声耦合的情况下，允许系统被排列。WST（波阵面纠正技术）条件被满足，以便阵列可以作为真正的线声源。任何线声源提供平滑的相位响应和良好的覆盖范围，而且在所有频率下无任何声音抵消。
  ARCS FOCUS 音箱可以由LA4 或LA8 放大控制器驱动和放大，这确保了系统线性化、单元保护和优化扬声器系统。

WST® Technology - Constant Curvature In 1995 L-ACOUSTICS® introduced constant curvature line sources with the implementation of the Wavefront Sculpture Technology® into the ARCS® system. At the heart of all ARCS® constant curvature enclosures is the DOSC® waveguide which morphs the spherical wavefront of the HF driver into a toric, isophasic wave. As a result, ARCS® can be arrayed with a perfect acoustic coupling as opposed to classic trapezoidal enclosures which interfere with each other and produce comb filtering degrading sound quality outside of the array axis. When compared to conventional line source systems, ARCS® has the advantage of offering a perfect control over horizontal coverage and a smooth tonal balance over all frequencies. The wavefront emitted horizontally by the enclosure allows uniform coverage in increments. The ARCS® line sources stand in-between variable curvature line sources, efficient over large distances and point sources based on coaxial technology, excellent for proximity applications. An ARCS® line source is best suited for medium throw applications, as a main or fill system.

Properties All ARCS® line sources provide high SPL with perfect acoustic coupling, a solid LF performance and constant tonal balance over distance. Systems can be deployed either as a horizontal array or as a vertical array. In the coupling plane, the ARCS® line sources yield a razor-sharp directivity pattern, particularly valuable to sector audience fields while avoiding reflective surfaces. In the other plane, they provide a smooth directivity pattern. Furthermore, the trapezoidal shape of ARCS® enclosures correspond exactly to their coverage value (15°, 22.5°, or 30°). By allowing an immediate visualization of the array coverage on-site, this feature almost eliminates the need for SoundVision design software: what you see is what you get!Variable curvature, large format (KUDO, V-DOSC and K1) ARCS® coverage scalability All ARCS® systems can be deployed either horizontally or vertically, with a total coverage angle proportional to the number N of ARCS® enclosures in the array. ARCS® can fit applications requiring narrow coverage (15°, 22,5°, 30°) such as fills, standard coverage (75°, 90°) for L/R FOH systems or extended coverage (105°, 120°) for central clusters and up to 360° for in-the-round designs. This exceptional scalability makes ARCS® a system capable of adjusting to any audience geometry, including the most complex ones.
