Variable Curvature Line Source
DOSCWith 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 VentingAll 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™ DSPPanflex 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.

Part of the K Series, K3i is a full range line source system designed for installed applications beyond 35m of throw. Housing the internationally recognized K2 performance into a compact enclosure, K3i is ideal for medium to large-scale venues where premium-tour sound and limited footprint prevail, such as large concert halls, clubs, congress centers and sport venues.
With exceptional bandwidth for its size - 42 Hz to 20 kHz - K3i system can be used as a stand-alone line source boasting strong output and reinforced LF contour. K3i can be supplemented by its companion subwoofer KS28 for increased LF capability or infra reinforcement.
K3i features PanflexTM offering four horizontal dispersions: 70° or 110° symmetrical or 90° asymmetrical on either side. With Panflex and inter-element angles ranging from 0.25° to 10°, the K3i line source coverage can be precisely tailored to any audience geometry.
Designed as a two-way active loudspeaker, K3i requires only two amplified controller channels for efficient amplification and optimal use of the Autosolver tools.
“Our design team created a dual-12-inch-based system with the form factor and price of a 10-inch design, without the inherent performance compromises of 10-inch loudspeakers. K3i offers long-throw, full-range performance in a compact, accessible package, tailor-made for small to mid-capacity venues. It is a ‘no compromises’ tool, that comes with the right arguments for integration: lightweight, sleek design, color program, and adjustable coverage.”
