Meyer Sound MM-4XPD-3, 4" Active Speaker, Hypercardioid, 3-Pin Input

The Meyer Sound MM-4XPD-3 is a self-powered miniature loudspeaker (with IntelligentDC technology) for high-quality distributed systems. This Meyer Sound MM-4XPD-3 is housed in a compact aluminum enclosure, the Meyer Sound MM-4XPD-3 is especially perfectly suitable for installations involving space limitations and visibility concerns, such as fill and spot coverage, and hidden locations like chancel steps in houses 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. 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.

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 Meyer Sound MM-4XPD-3 having the added advantage of a hypercardioid coverage pattern. 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 113dB and a wide operating frequency range of 120Hz to 18kHz with very low distortion. 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.
