The Meyer Sound MM-4XPD directional loudspeaker was specifically
designed for high-quality distributed systems in highly reverberant spaces.
The directional polar pattern of the loudspeaker at low frequencies significantly
reduces the excitation of the room and increases the intelligibility of
The single 4-inch cone transducer, manufactured at Meyer Sound's Berkeley
factory, delivers an impressive maximum peak SPL of 113 dB, and has a

Meyer Sound's MM-4XPD amplifier and signal- processing circuits are designed
to store DC power and tolerate voltage drops, thereby accommodating light-gauge
cables and long cable runs. The Meyer Sound MM-4XPD receives balanced

Meyer Sound MM-4XPD loudspeaker systems require an external MPS Power
Supply. The Meyer Sound MPS-488HPe
rackmountable 8-channel power supplies are ideal for larger installations
with multiple loudspeakers and distributes power and audio signal, while
the compact MPS-481
power supply is designed for powering single loudspeakers individually.
Meyer Sound's MM-4XPD extruded aluminum enclosure acts as a heat sink
to dissipate heat from the driver's voice coil. The enclosure is available
in standard white or black anodized finishes with a perforated steel grille.
The Meyer Sound MUB-MM4XP U-bracket is available for mounting the loudspeaker
on walls and ceilings at adjustable angles.
