無論是采取固定安裝，在巡演時作為獨立的主擴聲系統，或者作為WST®線聲源陣列的補聲系 統，ARCS®II都有效發揮WST®技術的所有功率，為聽眾帶來獨特的近場聆聽體驗。
從建立之初，L-ACOUSTICS就堅持不斷創新和采用科學的方法的宗旨。L-ACOUSTICS最初植根于在物理和基礎聲學方面，L-ACOUSTICS被譽為現代線聲源陣列的鼻祖，這歸功于它發明的波陣面糾正技術（Wavefront Sculpture Technology）和傳奇性的V-DOSC系統。
然而隨著時間的推移，L-ACOUSTICS已經把它的研究活動拓展到結構工程，動力電子技術，信號處理和數字網絡領域。L-ACOUSTICS還研發了自己內部的模擬建模工具，并通過大量的實驗以驗證模型的正確性。此外，L-ACOUSTICS經常在科學界發布所取得的研究成果。作為一個工程技術推動型的團隊，L-ACOUSTICS是音頻制造行業最受尊敬的組織之一。

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.
