1/1
The HMS12 highpower surround loudspeaker
is optimized for use in cinemas, theatres, and
rerecording stages. The selfpowered, fullrange
HMS12 maintains a wide dynamic range, full
fidelity, and clarity during the most demanding of
digital soundtracks. As part of Meyer Sounds EXP
cinema series, the HMS12 integrates seamlessly
with Acheron screen channel loudspeakers, as
well as with other HMS surround loudspeakers.
Boasting a wide frequency range of 59 Hz to 18 kHz
and a maximum peak SPL of 130 dB at 1 meter
with very low distortion, the HMS12 ensures that
the full intensity and nuance of cinema surround
channels reach each listener without compromise.
The HMS12s transducers include a 12inch low
frequency, longexcursion cone driver and a
3inch diaphragm highfrequency compression
driver on a symmetrical constantdirectivity
100degree horn that delivers exceptional
consistency. The proprietary drivers designed
and manufactured at Meyer Sounds headquarters
in Berkeley, California are powered by two
channels of onboard amplification that include
an active crossover, driver protection circuitry,
and correction filters for flat phase and frequency
responses.
The versatile HMS12 can be mounted on walls
or ceilings at fixed or adjustable angles with the
optional wallmount brackets (fixed or adjustable),
hinge bracket, Ubracket, and halfyoke, allowing
the unit to be deployed per the requirements of any
surround or immersive surround format.
HMS-12 : High-Power Cinema Surround Loudspeaker
PRELIMINARY PRODUCT INFORMATION
DC power and balanced audio are received by the
HMS12 from a Phoenix 5pin male connector
on its top panel. Powering the unit from an
external source eliminates the need for wiring
conduits while still preserving the advantages of
selfpowered, biamplified loudspeaker systems.
The HMS12s amplifier and signalprocessing
circuits store DC power and tolerate voltage
drops, thereby accommodating lightgauge
cables and lengthy cable runs.
1. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
2. Free field, measured with 1/3-octave frequency resolution at 4 meters.
3. Measured with music referred to 1 meter.

Mounting
The MPS488HP external power supply is availabl
for conveniently distributing DC power and balanceaudio to up to eight HMS12 loudspeakers. The us
of composite multiconductor cables allows a singl
cable to carry both DC power and balanced audio
to each surround loudspeaker.
Meyer Sounds industry leading selfpowered
loudspeaker technology not only delivers unparallele
and consistent audio fidelity but also simplifie
installation, whether designing a new room from
scratch or adding surround channels to an existing
setup. The HMS12s textured finish and black clot
grille blend smartly with any theatre decor.
