Variable Curvature Line Source


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).

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.

Panflex™ DSP

Panflex DSP was introduced with the K2 system in 2014. Combining L-Fins and DSP, it offers the possibility to change the horizontal directivity pattern from wide to narrow, from symmetric to asymmetric. With Panflex, a variable curvature line source can now match the complex shape of any audience geometry, both in the vertical and horizontal planes, further minimizing noise pollution.

K2 / K1-SB


K2 offers the same pristine, powerful sonic signature as K1 – in a lighter, more compact format and with 10° inter-element angles for maximum versatility. K2 can be deployed as a complement to K1 or as a standalone system for events or installations with audiences of up to 20,000, without sacrificing power.

Lightest in its class, K2 can be flown even under the most stringent rigging limitations. And with the exclusive L-Acoustics Panflex adjustable horizontal directivity, K2 focuses sound coverage on the audience only, handily addressing the most challenging acoustic environments or noise pollution issues for outdoor events.
With integrated rigging compatible with K1 and the entire K System, technicians the world over seek out K2 for its lightning fast set up.

“The K2 can throw the sound way more than I ever imagined it could. The signature transition between the K1 and the K2 is really nice and smooth. It is truly unbelievable for the size and weight of the box, they’ve really outdone themselves! The fact that it is very easy to rig is a really important feature; it makes all the difference for a big production like this. Seriously, it takes 10 minutes to get in the air!”
