The Meyer Sound DF-4 is a medium-throw downfill loudspeaker designed for supplementing coverage in flown sound reinforcement systems. It provides even coverage to the areas below and to the immediate front of arrayed loudspeakers, and exhibits frequency and phase response similar to other Meyer Sound loudspeakers that are typically used in medium-to-large arrays. The enclosure shape and the high-frequency horn coverage pattern are carefully selected to ensure adequate coverage, minimize overlap and streamline rigging procedures.

The compact, vented DF-4 enclosure houses a direct-radiating 15-inch low-frequency driver, and a 4-inch diaphragm compression driver coupled to a symmetrical 50° horn. The two-channel class AB/H power amplifier employs complementary power MOSFET output stages and produces a total burst output of 1240 watts (620 watts per channel). The integrated, field-replaceable amplifier and control unit is equipped with TruPower limiting technology, and the power supply incorporates Intelligent AC for fail-safe international operation. Phase-corrected, active signal processing circuits help maintain excellent performance and reliability, while the high input CMRR permits long signal runs over shielded twisted-pair cable.

The DF-4 cabinet is coated with a textured black finish. The DF-4 is compatible with Meyer Sound’s RMS remote monitoring system, which provides monitoring of system performance over a Windows-based network.
