Meyer MM-4XP Powered Speakers
This miniature self-powered loudspeaker is designed for high-quality distributed systems. With its compact aluminum enclosure, the MM-4XP is especially suitable for installations involving space limitations and visibility concerns.
The loudspeaker’s proprietary 4-inch cone transducer delivers an impressive maximum peak SPL of 113 dB (measured with music referred to 1 meter), and has a wide operating frequency range of 120 Hz to 18 kHz with very low distortion, exhibiting the same high intelligibility and flat frequency and phase responses for which Meyer Sound loudspeakers are known. Peak and rms limiters regulate loudspeaker temperatures and excursion, ensuring that the MM-4XP performs exceedingly well even when driven into overload.
The loudspeaker's amplifier and signal-processing circuits are designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and long cable runs. Balanced audio and DC power are delivered through a sealed SwitchCraft® EN3™ 5-pin male connector on the rear panel, ensuring protection against harsh environmental conditions when the MM-4XP is installed outdoors.
The MM-4XP’s extruded aluminum enclosure acts as a heat sink to dissipate heat from the driver's voice coil.
MM-4XP loudspeaker systems require an MPS-488 external power supply.
