The DLF Series implements techniques originally developed for directional radio transmitting antennas. Drivers are oriented with a vertical spacing which defines an octave wide controlled coverage band, below which the loudspeaker behaves as a conventional LF system. Steering of the LF lobe can be achieved by applying a signal delay to the lower driver.
A system combining DLF dipoles and ribbon-based CLA, SLA and ULA Series loudspeakers, delivers high impact, full-range reinforcement to the audience in a compact form.
