MEYER SOUND MM-4XP: Self Powered Miniature Loudspeaker

The Meyer Sound MM-4XP miniature loudspeaker is a self-powered loudspeaker designed for high-quality distributed systems. Housed in a compact aluminum enclosure, the Meyer Sound 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.


  • Extremely compact enclosure
  • Self-powered
  • Wide-range frequency response at ultralow distortion
  • High speech intelligibility, and punch and bandwidth for music
  • Amazing SPL/size ratio
  • Enables runs of hundreds of feet of light-gauge cable


  • Space-sensitive fill and spot coverage
  • Reinforcement concealed in steps and other hidden locations
  • High-quality distributed systems for paging and music
  • Small, portable systems for corporate AV
  • Exhibit audio for museum displays

The Meyer Sound 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 Meyer Sound 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 Meyer Sound 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 Meyer Sound MM-4XP performs exceedingly well even when driven into overload.

The Meyer Sound 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 Meyer Sound 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 Meyer Sound MM-4XP is installed outdoors.

Meyer Sound MM-4XP loudspeaker systems require an external Meyer Sound MPS Power Supply. The Meyer Sound MPS-488HPe | MPS-488HPp rackmount 8-channel power supplies are ideal for larger installations with multiple loudspeakers and distributes power and audio signal, while the compact Meyer Sound MPS-481 power supply is designed for powering single loudspeakers individually.

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

The Meyer Sound 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 Meyer Sound MUB-MM4XP U-bracket is available for mounting the loudspeaker on walls and ceilings at adjustable angles.
