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 audio-visual, where intelligibility is critical.
Directional hypercardioid pattern provides 10 dB of attenuation between the front and rear of the loudspeaker, even at low frequencies
Directional pattern reduces room excitation, desirable in highly reverberant spaces
Extremely compact size fits in small spaces
Patent-pending, passive, single-driver directional technology minimizes energy consumption, weight, and cabinet volume
