K1 large format WST line source
The K1 enclosure is the full-range element of a large format WST
®
line source with variable curvature. The K1 features
two 15" speakers mounted in a bass-reex enclosure, four 6.5" high-efciency direct radiating speakers, and three 3"
diaphragm compression drivers coupled to individual DOSC
®
waveguides. The transducers are implemented in a K-
shape conguration. The K1 enclosure is based on a 3-way active design with 2 LF sections, 1 MF section and 1 HF
section, each one at the nominal impedance of 8 ohms. The K1 enclosure is made of rst grade Baltic birch plywood to
ensure maximum acoustical and mechanical integrity. A four-point rigging system is integrated into the cabinet.
The K1 enclosure operates over the nominal frequency range of 35 Hz to 20 kHz. The frequency response of the system
can be extended down to either 30 Hz or 25 Hz with the addition of the dedicated K1-SB extension, or the KS28SB28
subwoofer, respectively. The K1 generates a symmetric horizontal coverage of 90°.
The rigging system allows vertically assembling K1 enclosures with various inter-element angles up to 5°, 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 fullled, so that such an array can be qualied 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 K1 system is driven by the LA8LA12X amplied controller which ensures active system linearization, intelligent
transducer protection, and optimization of the loudspeaker system in its different operating modes. The acoustic
performances of the system will depend upon the used preset and the chosen physical conguration
