DSP Subwoofer
Product highlights
Meridian’s first DSP Subwoofer,
DSW delivers powerful,
authentic bass with room-filling
performance to enhance both
music and movie soundtracks.

Ideal for use with a Meridian
Surround Controller or in systems
incorporating Audio Core 200.
Designed with the power needed
to complement the bass response
of Meridian Digital Active
Loudspeakers, which already
exhibit impressive bass extension.
DSW is a powerful and dynamic subwoofer
offering exceptional performance in a wide
range of Meridian system applications.
Designed to complement Meridian’s Digital
Active Loudspeakers, DSW is an extremely
powerful unit. It is ideal for use in a
complete surround-sound configuration of
DSP3200 or DSP3300 loudspeakers, for
example, or to complement larger Meridian
loudspeakers such as the DSP5200.
DSW subwoofers can even be paired with
DSP7200 loudspeakers where appropriate.
The unit includes full thermal protection
and an advanced, sturdily-constructed,
long-throw, high-power 12in drive unit. It is
driven by a powerful closed-loop Class D
amplifier capable of delivering up to 600W.
The driver points downwards and thus
removes any tendency to sideways cabinet
Designing a Meridian Subwoofer
The design criteria for a subwoofer to
complement Meridian Digital Active
loudspeakers differ significantly from those
of a subwoofer designed for conventional
systems. To begin with, Meridian Digital
Active Loudspeakers already include a
significant deep bass extension that far
exceeds the capabilities of conventional
loudspeakers of a similar size.
Thus, to make a meaningful contribution
to the bass reproduction of the Meridian
system in which it is installed, a Meridian
subwoofer design must generate a
significant level of low bass. This, in turn,
dictates a larger, more powerful driver
and appropriate cabinetry. The result is a
digital subwoofer that is not only suitable
to complement DSP3200 and DSP3300
systems but larger loudspeakers in the
range, such as the DSP5200, as well.
New high-power long-throw 12in
driver and amplifier combination
delivers maximum performance
under total DSP control, for full,
impressive yet fully-integrated
Downward-facing driver
minimises lateral movement.
Extremely strong internal cabinet
construction for maximum rigidity
at high power levels.
Ideal for the most bass-heavy
music and the most powerful
action movie soundtracks.
Simplified configuration
An additional benefit of the Meridian
approach is that the subwoofer does not
require the phase control found on many
conventional active subwoofers. This is
because the phase control is designed to
compensate for performance differences
in an unknown system that could include

x 12in long-throw bass driver, facing
the system. A three-position selector switch
marked ‘1 1+2 2’ allows the unit to be set
to pick up the appropriate digital signal
from the SpeakerLink feed.
In most cases, the phase control is in fact
an attempt to compensate for an inability
to establish the correct delay setting in
signals sent to the main loudspeakers.
In a Meridian surround system, however,
loudspeaker delay is configured as part of
the setup and installation of the surround
controller, so this issue does not arise. As a
result, the phase control can be dispensed
with as it is completely unnecessary.
Typical applications
In addition to being suitable for use with
any Meridian Surround Controller, DSW
is ideal for use in a system incorporating
Audio Core 200 – for example with a pair
of DSP3200 loudspeakers. Here, the
Audio Core 200 can be used to select the
crossover setting below which audio to the
DSP3200 loudspeakers is rolled off, and
the DSW is activated.
DSW is also a perfect complement for
larger Meridian Digital Active Loudspeakers
such as the DSP5200. In addition, multiple
DSW subwoofers can be used in a
DSP7200-based system.
In normal operation, the bass end of the
main loudspeakers is rolled off and all
bass is handled by the subwoofer(s).
Alternatively, a surround system including
DSW can be operated in “Bass Heavy”
mode – ideal for action movie soundtracks,
for example, and certain types of music –
where both the main loudspeakers and the
subwoofer are configured to handle bass

In the case of a surround system with a
single subwoofer where the Centre and
Subwoofer loudspeaker feeds are carried
by the same cable, the switch is set to pick
up Channel 2, which is generally defined
as being the Subwoofer channel in the
surround controller. In the case of a system
with multiple subwoofers, 1 or 2 can be
selected to pick up the left or right channel
feed according to the position of the unit. In
the case of an Audio Core 200 system, the
switch would be set to 1+2 so as to handle
the bass for both left and right channels.
Cabinet and construction
Despite utilising a 12in driver, the DSW
is relatively compact and yet capable of
very high performance. To manage the
level of power the unit can produce, the
plywood cabinet is extremely robust, with
exceptionally strong, carefully-positioned
internal struts. In addition, the driver itself is
mounted in a “nest” of internal ribs that hold
it firmly in position for the maximum stability
and control.
