For years, Meridian loudspeakers
have offered the highest levels of
performance available – the result of
careful design, the highest-quality
drivers and components, transparent
crossovers and rigid, low-coloration
enclosures in both Active and Digital
Active designs. Now we have paid the
same level of attention to the design of
loudpeakers for installation purposes,
including in-wall, flush-mount and
on-wall configurations. These offer
full Meridian performance for systems
where the use of floor-standing models
is impossible or inappropriate.

The SW300 series of installation
subwoofers complements the other
members of the 300 Series of wall­mounting systems to allow exceptional
flexibility of configuration.

The SW320 is the smallest of a planned
series, with an enclosure that includes
an 10in bass driver and an 10in
Auxiliary Bass Radiator and is fed by
a single cable pair. The enclosure is
identical in size to the 320 in/on-wall
system and is available in in-wall or
flush-mount configurations. The back
box is under a foot wide and under

4in deep, making it ideal for use in
standard stud walls.

The rigid enclosure minimises wall
and cavity excitation so you hear the
speakers, and not wall resonances. A
black, paintable fabric-covered low­resonance grille is included.

The SW320 is driven by the C52 Active
Subwoofer Controller, a 2U rack­mounting unit with a conservatively­rated linear power supply and low­field true toroidal power transformer.
The controller contains two amplifier
modules each delivering 180W into 4Ω
(the impedance of the speaker unit),
thus enabling a single controller to drive
two subwoofer speaker units. Multiple
analogue and 2-channel digital inputs
are provided and the unit integrates
completely into a Meridian installation
while offering full compatibility with
third-party systems.

Meridian installation loudspeakers
deliver the performance of a stand­alone design in a discreet enclosure
with minimal visual impact – and
awesome power.
