The MM-4XP miniature loudspeaker is a self-powered loudspeaker designed for high-quality distributed systems. Housed in a compact aluminum enclosure, the MM-4XP is especially suitable for installations involving space limitations and visibility concerns, such as fill and spot coverage, and hidden locations like chancel steps in a house of worship. Its flexible and easy-to-configure mounting options, as well as its ability to effortlessly reproduce both speech and music, make it an excellent choice for fixed applications, theatrical presentations (stage lip frontfill), and small portable systems for corporate AV solutions.

The MM-4XP meets the same exceptional performance standards established by its predecessor, the MM-4, and adds the advantages of self-powered systems, with onboard amplification and signal processing. The MM-4XP's proprietary 4-inch cone transducer, manufactured at Meyer Sound's Berkeley factory, delivers an impressive maximum peak SPL of 113 dB, and has a wide operating frequency range of 120 Hz to 18 kHz with very low distortion. The MM-4XP exhibits the same high intelligibility and flat frequency and phase responses for which Meyer Sound loudspeakers are known. Peak and rms limiters regulate loudspeaker temperatures and excursion, ensuring that the MM-4XP performs exceedingly well even when driven into overload.

The MM-4XP's 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 MM-4XP receives balanced audio and DC power from a SwitchCraft EN3 connector on its rear panel. The sealed, 5-pin EN3 connector provides protection against harsh environmental conditions when the MM-4XP is installed outdoors.

MM-4XP loudspeaker systems require an MPS-488HP external power supply. The MPS-488HP rackmount 8-channel power supply is ideal for larger installations with multiple loudspeakers and distributes power and audio signal, while the compact MPS-481 is designed for powering single loudspeakers individually.

Powering the MM-4XP from a unipolar external power source reduces induced noise significantly and eliminates the need for wiring conduits.

The MM-4XP's 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. It can also be custom painted to match specific color schemes. The MUB-MM4XP U-bracket is available for mounting the loudspeaker on walls and ceilings at adjustable angles.
