Constant Curvature Line Source

Laminar Venting

All current L-Acoustics loudspeaker enclosures with low-range capacities feature laminar vents which provide high SPL while eliminating turbulence noise. This technology was implemented for the first time in 2007 in the SB28 subwoofer, and has been included in K1, K1-SB, K2, SB15m, SB18(i/m), and the X Series.


With the proprietary DOSC waveguide, the L-Acoustics V-DOSC system was the first line array to operate coherently across the whole audible frequency range. Since 1993, this major technological innovation is at the heart of every L-Acoustics line source element, with specifically tailored DOSC waveguides for constant curvature arrays (ARCS systems) or variable curvature arrays (K systems).

Configurable L-Fins

A15 Wide

The new ARCS A15 and A10 systems deliver renowned L-Acoustics concert performance and reliability for audiences from 50 to 5,000. Mounted on a pole, stacked on the companion KS21 or flown in vertical or horizontal arrays, the new ARCS family combines plug-and-play ease and international market acceptance. This versatile solution, with adjustible directivity, scales with the needs of your company and is your gateway to the L-Acoustics rental network. ARCS can take you anywhere you want to go.

“We see the new ARCS line of products as the perfect way to welcome providers into the L-Acoustics rental network. The versatility and scalability of ARCS is really a ‘choose your own adventure’ scenario that only leads to happy endings. We look forward to seeing new customers approach the live events market in creative ways that allow them to capitalize upon their initial investment quickly and take their rental business to the next level.”
