The D6-B is a coaxial loudspeaker, with a compression driver concentrically located so that high frequencies emerge through the center of the low-frequency driver via a precisely contoured Tru-Phase HF waveguide. Community says this provides consistent, wide dispersion up to 16kHz. The D6-B can also be tapped at 8-ohm or 70V/100V configurations.
Here are all the detailed specs.
