The MM-10 miniature subwoofer delivers
expanded low frequency for applications
that require excellent audio quality from
a compact system. Designed primarily as
a companion to Meyer Sound's MM-4XP
miniature loudspeaker, as well as the UP-4XP
ultracompact loudspeaker, the MM-10 allows
system designers to create full-range systems
where space limitations are a concern.
The MM-10 features an operating frequency
range of 33 Hz to 228 Hz with a conservatively
rated maximum peak SPL of 123 dB. The
MM-10 bass reflex cabinet houses a single
10-inch driver and a single-channel power
amplifier complete with onboard processing,
including a crossover, driver protection, and
frequency and phase correction. The built-in crossover accepts full-range signals,
facilitating basic daisy-chaining for signal
distribution, eliminating the need for external
crossovers in small setups.
The MM-10 subwoofer is available from the
factory in three models — the MM-10XP,
MM-10AC, and MM-10ACX — each offering
different internal configurations and audio
and power connectors (which cannot be
upgraded).
The MM-10XP model is powered by an
external 48 V DC power supply, eliminating the
need for wiring conduits while still preserving
the advantages of self-powered loudspeaker
systems. The unit's onboard amplifier and
signal-processing circuits were designed to
store DC power and tolerate voltage drops,
thereby accommodating light-gauge cables
and lengthy cable runs. The MM-10XP is
available with either a Phoenix 5-pin male
or sealed SwitchCraft® EN3™ male connector
for receiving balanced audio and DC power.
The EN3 connector is ideal for outdoor, all-weather use.
MM-10XPs require an MPS-488HP external power supply. The single-space 19-inch rack
unit receives balanced audio from its XLR
female inputs and routes the audio, along
with 48 V of DC power, to its channel outputs.
The channel outputs — equipped with either
Phoenix 5-pin male connectors or EN3 5-pin
female connectors — can deliver DC power
to up to eight MM-10XP subwoofers at cable
lengths of up to 150 feet with just 1 dB of loss
in peak SPL using 18 AWG wire. The use of
composite multiconductor cables (such as
Belden 1502) allows a single cable to carry
both DC power and balanced audio to the
MM-10XPs. Longer cable runs are possible
for moderate applications that don't drive
the subwoofers to maximum output, or for
installations with heavier wire gauges.
The MM-10AC model is ideal for fixed
installations and portable applications where
AC power is readily available to power the
unit. The MM-10AC includes an internal power
supply and locking PowerCon connectors for
AC input and AC loop output (for powering
additional MM-10AC subwoofers). The
MM-10AC receives audio from an XLR female
input, and also includes an XLR male loop
output for daisy-chaining audio signals.
The MM-10ACX model includes onboard
DC power and audio routing for driving a
pair of MM-4XP miniature loudspeakers, or
a single UP-4XP ultracompact loudspeaker,
effectively placing the MM-10ACX at the heart
of an extremely capable compact, full-range
loudspeaker system. Three XLR female inputs
are included for receiving audio independitely
for the subwoofer and satellite loudspeakers.
The two output connectors for the satellite
loudspeakers are available with Phoenix
5-Pin male or EN3 5-pin female connectors. In
addition, a two-channel signal can be patched
to the satellite inputs and summed and routed
to the subwoofer with the input select switch.
Other options for all MM-10 models include
the MUB-MM10 U-bracket for mounting the
subwoofer on ceilings and walls; weather
protection, complete with rain hoods, for
outdoor, all-weather use; and custom color
finishes for installations and applications with
specific cosmetic requirements.
