Meyer Sound MM-4XPV-3, 4" Active Speaker, Volume Control, 3-Pin Input

Meyer Sound MM-4XPV-3, 4" Active Speaker, Volume Control, 3-Pin Input

The Meyer Sound MM-4XPV-3 is 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-4XPV-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 1 kHz 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. The Meyer Sound MM-4XPV-3 is also directional miniature self-powered loudspeaker with IntelligentDC technology was specifically designed for higquality distributed systems in reverberant spaces. The directional polar pattern of the MM-4XPD, especially at low frequencies, significantly reduces room excitation and increases intelligibility. In addition, the Meyer Sound MM-4XPV-3 is flexible and easy-to-configure mounting options, as well as its ability to effortlessly reproduce both speech and music, make the MM‑4XPD an excellent choice for large distributed systems, theatrical presentations, museums, and small portable systems for corporate audio-visual, where intelligibility is critical.

The Meyer Sound MM-4XPV-3 meets the same exceptional performance standards as the MM‑4XP with the added advantage of a hypercardioid coverage pattern. 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. Even at low frequencies, the breakthrough technology yields 10dB of attenuation at the rear of the loudspeaker whileretaining directional dispersion at high frequencies.
