L-Acoustics KARA Line Array Loudspeaker

L-Acoustics KARA Line Array Loudspeaker

The KARA modular line source element has an operating frequency bandwidth from 55 Hz to 20 kHz. This response can be lowered down to 32 Hz with the addition of the SB18 low frequency extension. KARA features a 2-way, bi-amplified design and is equipped with 2 x 8” neodymium LF speakers in a bass-reflex tuned enclosure. The HF section features a 3” neodymium diaphragm driver coupled to a DOSC® waveguide. The K-shaped coplanar transducer configuration generates a symmetric horizontal coverage of 110° without secondary lobes over the entire frequency range. The combination of coplanar symmetry and DOSC® waveguide allows the system to fulfil the 5 WST® criteria. Any KARA line source can be curved up to a maximum of 10° for each element without breaking the inter-element acoustic coupling. The KARA enclosure is made of first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity. The 4 point rigging system allows suspending up to 24 KARA in a single array.
