With the increasing demand for in-wall
and ceiling mounted loudspeaker
designs, particularly in home theatre
applications, Meridian has released a
new, compact model, the DSP320, to
complement the existing DSP520 fullrange loudspeaker.
Developed from the successful DSP520, the
DSP320 is designed for both in-wall and inceiling use and is designed to deliver similar
tone qualities and compatible performance.
It can also be easily integrated into systems
that combine Meridian’s free-standing DSP
Loudspeakers with in-walls.
Like the DSP520, the DSP320 has been
developed specifically to deliver wide
dispersion for maximum listening area, with
minimum unwanted diffraction thanks to
careful baffle and grille design. The on-board
DSP provides thermal and dynamic bass
protection with very accurate transients,
ensuring that when the loudspeaker is played
at high levels, even over prolonged periods of
time, the loudspeakers always deliver a clean,
detailed and accurate sound.
Voicing compensation is included for
installation behind provided grille, or fabric
and screen material.
DSP320 includes two powerful Class D
amplifiers: 100W dedicated to the widerange driver, while a 150W amplifier powers
the bass driver.

Compact 300mm (12in) square*
design only 100mm (4in) deep*

performance in-wall (*approx)
Back-box and frame system allows

Fire-rated rough-in box with AC
connection and mounting hardware
Damped, high-rigidity aluminium
acoustic enclosure with internal
These amplifiers have been designed to
operate comfortably and run perfectly cool,
even at the highest listening levels.
The use of a wide-range driver across the
speech band helps create a loudspeaker with
an effortless sound that remains clear, open
and spacious, even at high listening levels.
Meanwhile, the bass end is crossed over at
200Hz, just as in the flagship DSP8000,
with a full-scale high-resolution Meridian
DSP crossover. Meridian’s unique suite of
proprietary technologies provides a lifelike
sound at all volume levels. DSP processing
throughout delivers a level of performance
matching that of a conventional loudspeaker
of eight times the physical volume, while
an ‘apodising’ upsampling filter delivers
maximum digital audio quality.
The in-wall systems are built into a
completely integrated, compact (total
302.5mm/11.9in square, 315mm/12.5in
square including optional grille frame)
all-metal frame and enclosure system,
with carefully-calculated internal volume to
provide the required acoustic characteristics
for the drivers. This self-contained enclosure
mounts to a frame which is in turn mounted
into the rough-in box, which is designed for
mounting into new-build partition and stud
style wall. It can alternatively be retrofitted
into stud or brick/stone-built walls or ceilings.
The rough-in box provides a fireproof
enclosure that includes a box for power entry.

High rigidity aluminium baffle with
Bass/Wide Range drive units
and high contact magnetic grille

White scrim under high precision
plated steel, paintable, matt white
grille.
DSP-based design delivers
superior performance to
conventional designs – equivalent
to an enclosure of eight times the
physical volume.
Features “Racetrack” oval bass
driver, and the same 85mm widerange driver as the DSP520, for
full-frequency response
All aspects of the design including
baffle and grille have been
developed for maximum dispersion
and listening area plus minimum
unwanted diffraction

DSP320 Rough-in box dimension drawing
Technical Note TN69
Power is brought into the rough-in box and
fed to an IEC connector inside the power
box that feeds the loudspeaker. Signal inputs
and outputs are brought into the back box
via grommets through knockouts included
in several locations around the box. The
loudspeaker assembly includes two RJ45
SpeakerLink connectors, one for input and
one for output, allowing the units to be wired
home run or daisy-chain.
During the installation process, the rough-in
box may be mounted directly into the wall, for
example by attaching it directly to woodwork
or brickwork, or secured via mounting wings
that fix to the side of the rough-in box,
which give additional stability. It can also
be attached to the frame, whose return
always lies on the wall surface, clamping the
entire assembly in place. The loudspeaker
enclosure itself then mounts on to the frame,
and the perforated steel grille attaches
to rubberised magnets in the aluminium
extrusion that forms the front panel of the
loudspeaker enclosure.
The paintable magnetic grille also has
locating pins top and bottom that fit into
holes in the extrusion. All the elements –
rough-in box, frame, loudspeaker enclosure,
included scrim and grille – include room for
adjustment (except when flush-mounted) so
that the entire assembly can be fitted with
precision into almost any type of wall.
The rough-in box kit includes a template to
determine mounting positions, plus a mask
to protect the box during plastering, etc,
ensuring simple, flexible and easy installation.
The drivers are mounted into the front
extrusion of the enclosure itself, while a
separate upper case holds the electronics,
consisting of DSP, digital audio converters
and an individual Class D amplifier per driver.
A mounting position is provided for the fitting
of a Media Source 200 unit to the rear of the
enclosure enabling the simple construction
of a single zone for a Meridian Digital Media
System.
The front of the extrusion carries the on/
off rocker switch, fuse holder, an infra-red
receptor window and a three-way (LeftMono-Right) channel selector rocker switch.
A LED indicator shows the loudspeaker
power status.
