The DSA-4 Pole Mount Adaptor holds up to three DVA T4 or T8 or K5 modules on single pole. A set screw adjusts the tilt angle smoothly rather than in stepped increments, enabling ultra-precise alignment. A scale on the side of the adaptor indicates the selected angle. Paired with an S10 subwoofer, this adaptor makes it so easy to set up three-way systems for smaller applications
