The MM-4XPD directional miniature self- powered loudspeaker, with IntelligentDC technology, was 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. Its 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 AV, where intelligibility is critical.

The MM-4XPD 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 10 dB of attenuation at the rear of the loudspeaker while retaining directional dispersion at high frequencies.
