L-Acoustics K2

Описание

The K2 is the full range element of a WST line source with variable curvature and adjustable horizontal directivity. The K2 loudspeaker enclosure is based on a 3-way active design. It comprises 4 input sections: 2 LF and 1 MF at a nominal impedance of 8 ohms, and 1 HF at a nominal impedance of 16 ohms. It features two 12” speakers and four 6.5”, all direct-radiating neodymium speakers mounted in a bass-reflex enclosure, and two 3” neodymium diaphragm compression drivers coupled to individual DOSC waveguides and adjustable directivity fins. The transducers are implemented in a K-shape configuration. The cabinet is made of machined first grade Baltic birch plywood combined to die cast aluminum side panels to ensure maximum acoustical and mechanical integrity while reducing weight to the minimum. A four-point rigging system is integrated into the cabinet.

The K2 enclosure operates over the nominal frequency range of 35 Hz to 20 kHz. Its LF resources can be reinforced with the dedicated K1-SB extension and its bandwidth can be extended down to 25 Hz with the SB28 subwoofer. In the horizontal plane, the directivity is adjustable down to 300 Hz, with two symmetric settings (70° or 110°) and two asymmetric settings (90° as 35°/55° or 55°/35°).

The K2 rigging system allows vertical assembly of enclosures with various inter-element angles (up to 10°), constituting a line array with variable curvature. The combination of the coplanar symmetry and the DOSC waveguide in the HF region ensure a perfect acoustic coupling between the elements of an array. The WST (Wavefront Sculpture Technology) criteria are fulfilled, so that such an array can be qualified as a true line source. Any WST line source provides a smooth tonal response and a coverage that is free of secondary lobes over the entire frequency range.
The K2 is driven and quad-amplified by the LA8 or LA4X controller with factory presets which ensure linearization, protection, and optimization for the loudspeaker system.
