Meyer Sound MM-4XPV-3, MM-4XPD-3 Data Sheet
DATASHEET ULTRA
MM-4XP Miniature Loudspeaker
Meyer Sound designed the MM‑4XP self‑powered miniature
loudspeaker (with IntelligentDC technology) for high‑quality
distributed systems. Housed in a compact aluminum enclosure,
the MM‑4XP is especially 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.
The MM‑4XP’s proprietary 4‑inch cone transducer with on‑board
amplification and signal processing, manufactured at Meyer
Sound’s Berkeley, California factory, delivers an impressive
linear peak SPL of 111.5 dB with crest factor >16.5 dB
3
and a
wide operating frequency range of 120 Hz to 18 kHz with very
low distortion. The MM‑4XP exhibits the same high intelligibility
and flat frequency and phase responses for which all Meyer
Sound loudspeakers are known. Peak and rms limiters regulate
loudspeaker temperatures and excursion, ensuring the MM‑4XP
performs exceedingly well even when driven into overload.
With IntelligentDC technology, the MM‑4XP receives power
and balanced audio from a SwitchCraft
®
EN3™ 5‑pin male input
connector on its rear panel. The sealed EN3 connector provides
protection against harsh environmental conditions for outdoor
installations of the MM‑4XP. Meyer Sound designed the MM‑4XP’s
amplifier and signal‑processing circuits to store DC power and
tolerate voltage drops, thereby accommodating light‑gauge cables
and long cable runs.
MM‑4XP loudspeakers require a Meyer Sound external power
supply. The compatible MM‑10 ACX miniature self‑powered
subwoofer includes on‑board DC power and audio routing for

driving a pair of MM‑4XP miniature loudspeakers. The MPS‑488HP
IntelligentDC power supply is ideal for larger installations
with multiple loudspeakers; the single‑space rack‑mount unit
distributes DC power and balanced audio to up to eight MM‑4XP
loudspeakers or other compatible Meyer Sound low‑voltage
loudspeakers. Another option is the 1RU, 1/2 width rack‑mount
MPS‑482HP IntelligentDC power supply that offers two channels
of audio and DC power.
Meyer Sound’s RMS™ remote monitoring system, which provides
comprehensive monitoring of system parameters from a Mac
or Windows®‑based computer, is available as an option for the
MPS‑488HP.
The Meyer Sound power supplies can deliver DC power to
MM‑4XP loudspeakers at cable lengths up to 300 feet with just
1dB of loss in peak SPL using 18 AWG wire. The use of composite
multi‑conductor cables (such as Belden
®
1502 or equivalent)
allows a single cable to carry both DC power and balanced audio
to the MM‑4XP. Longer cable lengths are possible for moderate
applications that do not drive the loudspeakers to maximum
output, or for installations with heavier gauge wire. Powering the
MM‑4XP from a unipolar external power source reduces induced
noise significantly and eliminates the need for wiring conduits.
For information and specifications about the Meyer Sound power
supplies, refer to their respective datasheets.
The MM‑4XP’s extruded aluminum enclosure acts as a heat sink
to dissipate heat from the driver’s voice coil. The enclosure is
available in a black‑anodized or standard white‑painted finish and
includes a perforated steel grille frame. The enclosure can also
be custom painted to match specific color schemes. The optional
MUB‑MM4XP U‑bracket facilitates mounting of the loudspeaker
on walls and ceilings at adjustable angles.
