L-Acoustics DV-DOSC
The 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.

Description
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.
