L-Acoustics DV-Dosc Loudspeaker
L’acoustics HP PH 81 (loudspeaker 8″ – 16 ohms for dV-DOSC) (Parts) NEW IN BOX
Wavefront Sculpture Technology – WST
Dv-Dosc is a full-spectrum, coherent full range two-way loudspeaker system. L-Acoustics dV-DOSC Line Source element has an operating frequency bandwidth from 65 Hz to 20 kHz and this response can be lowered down to 35 Hz with the addition of the dV-SUB low frequency extension cabinet. The dV-DOSC system is a 2-way, bi-amplified design and is equipped with 2 x 8” speakers in a bass-reflex tuned enclosure. The HF section features a 3” diaphragm driver coupled to a DOSC waveguide. The V-shaped coplanar transducer configuration generates a symmetric horizontal coverage of 120° without secondary lobes over the entire frequency range. The combination of coplanar symmetry and DOSC waveguide in the HF region allows the system to fulfil the 5 WST® criteria, thereby allowing the wavefront of a dV-DOSC line source to be curved up to a maximum of 7.5˚ for each element without breaking the inter-element acoustic coupling. The dV-DOSC enclosure heart is made of first grade Baltic birch plywood with top and bottom aluminum plates to ensure maximum acoustical and mechanical integrity. The 4-point rigging system allows flying up to 24 dV-DOSC. The dV-DOSC system is driven by the dedicated LA8 amplified controller which ensures active system linearization, intelligent transducer protection, and optimization for three operating modes:
- The ‘‘FULL RANGE’’ mode designed for standalone dV-DOSC Line Source arrays or distributed applications.
- The ‘‘HIGH-PASS’’ mode designed for applications with SB118 and SB28 subwoofer extensions.
- The ‘‘LOW EXTENSION’’ mode designed for applications with coupled dV-SUB LF extension.
