The successor to L-Acoustics’ V-DOSC system, K2 offers K1 performance in a rescaled package that makes it flexibly well-suited for both permanent installation and touring applications, from theatre to stadium productions. The primary system components include the K2 full-range element with PANFLEX horizontal steering, operating from 35 Hz to 20 kHz; the K1-SB low-frequency element reinforcing LF contour down to 30 Hz or LF throw down to 35 Hz; and the SB28 low-frequency element extending the operating bandwidth down to 25 Hz. Every K2 system is complemented by the LA4X / LA8 amplified controllers or LA-RAK touring rack fitted with three LA8.
Boasting an unprecedented performance/weight ratio, and its fast captive rigging system, the K2 line source benefits from L-Acoustics’ Wavefront Sculpture Technology (WST) to achieve exceptional sonic performance. Inter-element angles can be set with laser-like accuracy up to a generous 10 degrees allowing the optimization of the vertical coverage with SPL smoothly spread across the audience.
K2 employs L-Acoustics’ new PANFLEX, a unique horizontal steering technology that combines mechanically adjustable fins with DSP algorithms effective from 300 Hz. Four different settings are possible: two symmetric (70° or 110°) and two asymmetric (90° as 35°/55° or 55°/35°). Narrowing or widening the horizontal directivity can serve many purposes: adapt to the width of the listening area, fit long and short distance coverage/SPL requirements, reduce or extend overlapping areas, and avoid reflecting surfaces.
By combining WST and PANFLEX L-Acoustics exclusively addresses the control of directivity in both vertical and horizontal planes. As a result, K2 can match the complex shape of any audience geometry with ideal sonic performance and minimum noise pollution.
Thanks to its three-way quad-amplified design and full range capability, the K2 enclosure can be deployed as a standalone line source. For applications demanding extreme LF impact (contour mode), or maximized LF projection (throw mode), K2 can be arrayed with its dedicated and flyable K1-SB LF extension. The K2 system can also address applications with demanding infrasonic reproduction when combined to the SB28 subwoofer. Before installation, any system configurations can be acoustically and mechanically modeled with L-Acoustics’ SoudVision 3D simulation software.
For touring applications, K2 can be associated to the LA-RAK, a universal distribution platform for power, audio signals and network that facilitates cross rental between rental companies. LA-RAK houses three LA8 amplified controllers and can be flown onto a K2 array. Other applications can feature LA8 amplified controllers. For high-end installation projects, K2 can also be driven by the LA4X amplified controller. The scheme authorizes fully discrete DSP treatment per section and maximum power headroom for the best possible sonic performance.
With its dedicated factory presets, the LA8/LA4X amplified controller constitutes an extremely advanced and precise drive system for the enclosures. All L-Acoustics amplified controllers feature the L-Drive thermal and over-excursion protection circuit.
Up to 253 LA8/LA4X amplified controllers can be connected together via the Ethernet-based L-NET protocol. LA Network Manager software allows online remote control and monitoring of all the connected units via a user-friendly and intuitive graphic interface and features the Array Morphing EQ. This exclusive tool allows the engineer to quickly adjust the tonal balance of the system to reach a reference curve or to ensure consistency of the sonic signature.
