MM-4XP Miniature Self-Powered Loudspeaker

MM-4XP: Effortlessly Amplify Speech and Music

Fill and spot coverage for systems with space limitations and visibility concerns such as clubs, restaurants, portable AV, or galleries or museum displays.

MM-4XPD: Directional Speaker for Highly Reverberant Spaces

Specifically designed for high-quality distributed systems in reverberant spaces, the directional polar pattern of the MM-4XPD, especially at low frequencies, significantly reduces room excitation and increases intelligibility.

Coverage Patterns

Patent-pending technology yields a high degree of attenuation between the front and rear of the loudspeaker, achieving a directional polar response using passive acoustical techniques, with the MM-4XP having the added advantage of a hypercardioid coverage pattern.

Cone Tranducer

The MM loudspeakers feature a single 4-inch cone transducer, designed and manufactured at Meyer Sound's Berkeley, California factory, delivering an impressive maximum peak SPL of 113 dB and a wide operating frequency range of 120 Hz to 18 kHz with very low distortion.

Self-powered Advantage

Self-powered technology eliminates amplifier racks, long loudspeaker cables, and any calibration of gain and crossover settings. The system can be rigged and ready in minutes.

Tough and Light Enclosure

The MM-4's extruded aluminum enclosure acts as a heat sink to dissipate heat from the driver's voice coil, and is available in a black anodized or standard white painted finish and includes a perforated steel grille frame. It can also be custom painted to match specific color schemes.

Efficient and Compact

Patent-pending, passive, single-driver directional technology minimizes energy consumption, weight, and cabinet volume. The optional U-bracket mounts the loudspeaker on walls and ceilings at adjustable angles.

Power Supply Means No Conduits

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

Intelligent DC for Long Cable Runs

The use of composite multiconductor cables allows a single cable to carry both DC power and audio. Powering the MM-4XPD from a unipolar external power source reduces induced noise significantly and eliminates the need for wiring conduits.
