excess of 120 dB, giving better intermodulation
performance, and offering a level of background
noise below 10 dB SPL.
Digital signal processing allows impossible
crossovers, with linear phase, steep slopes and
time delay compensation. Highly accurate phas-
ing between the drivers means that the beam
of the system can be steered for the best
experience at the listening position: there is even
an axis control that allows the mid-range
frequencies to be precisely tailored to
suit your height.
Meridians active bass extension
deepens the response of the
system without excessive woofer
excursion. At moderate volumes,
a psychoacoustially-correct fi lter
extends the bass response much
further than can be achieved
with an analogue speaker of
equal size, while at high volumes
dynamic DSP bass protection is
used to prevent overload.
Meridian DSP8000
Our Stereophile Class A rated
fl agship, the DSP8000, (see
cutaway drawing, left) is designed
to reproduce sounds at up to
full natural level while providing all the
resolution required by sources of up to
24bit and 192kHz. Such demanding
dynamic resolution called for a new ap-
proach to cabinet construction and selection
of advanced drive unit materials.
Each DSP8000 loudspeaker uses six high-ef-
fi ciency long-throw custom bass drive units.
These are mounted symmetrically in pairs on the
sides of the bass cabinet, cancelling vibration
in order to minimise interference with the mid-
range and treble units.
The mid-range unit incorporates a cone made
from a uniquely light and stiff combination of
polymers to give unparalleled transparency. The
whole electronic assembly is supplied from two
substantial toroidal transformers feeding high-
quality audiophile-grade capacitors.
The DSP8000 is built into a precision manufac-
tured cabinet, employing many innovative de-
sign techniques for exceptionally low coloration
and exquisite mid-range transparency.
The treble and mid-range drivers are mounted in
a separate sealed head assembly. The treble unit
is a semi-horn-loaded composite dome design
with a silver voice coil.
The head assembly is a sealed enclosure fabri-
cated from curved pressure-laminated panels,
each using multiple layers of selected woods
and metal to provide high stiffness and damp-
ing. Its narrow, tapered shape offers optimum
dispersion across a wide listening area. It is
supported atop the bass enclosure by three
machined feet.
Like the head unit, the bass cabinet is construct-
ed from laminated wood/metal panels with
extensive bracing. The front panel is fi nished
with 6mm glass and incorporates a window for
the matrix display and infrared remote control
sensor. The cabinet stands on triangulated
adjustable machined feet with provision for fl oor
spikes or skids.
DSP420 In-Wall DSP Loudspeaker
The DSP420 (see cutaway drawing, right) is a
truly active in-wall speaker with separate inter-
nal amplifi cation for high and low frequency
bands. The precision low feedback designs,
rated at 65 and 85 Watts respectively, are based
on those used in other Meridian DSP speakers.
Using carefully selected bipolar output devices,
they deliver exceptionally fast bass response and
high resolution, while the system as a whole of-
fers extremely low levels of noise and distortion.
The power supply includes a substantial toroidal
transformer and audiophile-grade capacitors.
These amplifi ers are coupled directly to the drive
units for the most effi cient delivery of power
and the best possible control of driver excursion.
Enclosed in a fully shielded housing, Meridians
unique DSP processing is performed on a spe-
cially-designed six-layer PCB using a powerful
100 MIPS Motorola DSP engine.
Thanks to this sophisticated audio computer,
the DSP420 provides high-technology features
identical to those found in the rest of the Merid-
ian DSP Loudspeaker family.
The bass drive units are two
parallel 5in woofers with
cast alloy chassis, carbon
fi bre cones and very large
shielded magnets that
provide excellent drive and
control.
The high frequency dome
tweeter has a Neodymium
magnet and a protective grille,
while an acoustically transparent
grille protects the front baffl e and
drive units from harm when installed.
Its powder fi nish means the grille can
be easily painted, helping the DSP420 to
blend in with its surroundings.
Meridian DSP7000
The Meridian DSP7000 (pictured on the front
page) is a smaller derivative of the DSP8000.
Each DSP7000 uses two multiple high-effi ciency
long-throw custom bass drive units.
The treble and mid-range drivers are mounted
in a separate acoustic enclosure. The treble unit
is a semi-horn-loaded composite dome design
with a silver voice coil, while the mid-range unit
uses a custom 160mm polypropylene driver.
The speakers are driven by four independent
high-power, low-feedback power amplifi ers,
powered by a substantial toroidal transformer
feeding audiophile-grade capacitors.
Like the DSP8000, each DSP7000 loudspeaker
is built into a precision manufactured cabinet,
which uses innovative design techniques to give
exceptionally low coloration and exquisite mid-
range transparency.
The ported enclosure is fabricated in a similar
way to the DSP8000. The front incorporates a
window for the matrix display and an infrared
remote control sensor. The cabinet stands on
three adjustable machined feet with provision
for fl oor spikes or skids.
Hear something to your advantage
Combining the multiple, audible benefi ts of
Meridians unique DSP loudspeakers with the
extraordinary sound quality and reproduction of
the G Series brings you the best of all possible
worlds. The G Series sources, such as the G07,
G08, G91 and G98 include digital outputs that
will drive Meridian DSP Loudspeakers directly in
stereo and, in some cases, surround, while the
G68 surround processor with Meridian Room
Correction is an ideal complement to a G Series
digital source and Meridian DSP Loudspeakers
for the ultimate digital surround experience.
Theres too much to say about the extensive
range of Meridian DSP Loudspeakers than
we have room for here, and there are several
other models available, such as the DSP5000,
DSP5500 (pictured overleaf) and DSP6000
Series. The DSP5000 and DSP5500 also include
horizontal centre-channel variants.

The illustration shows the G91 at the heart of a compact Meridian-based stereo DVD system. The Meridian DSP loudspeakers take their feed from the G91s digital preamp outputs, with the speaker volume controlled either by the G91s front-panel knob or via the remote.
With the G91, any kind of video display device can be supported, whether composite, S-Video, Component (progressive or interlaced) or even the latest interfaces such as HDMI or DVI. Dif-ferent video inputs are converted to all formats, so there is only need for one display connection.
With three stereo analogue inputs and four digital ins (two optical and two coax), the unit will support a wide selection of inputs. The G91 also includes surround outputs, allowing it to act as the centrepiece of a multichannel system.
DSP8000 -“ the inside story. The rigid enclosure, laminated from selected plywood and metal, has six coats of hand-fi nished piano lacquer. The six horizontally-opposed bass drive units neutralise cabinet resonance. The rear-mounted sealed DSP crossover and multiple power amplifi ers are mounted on a precision machined heat sink.
The DSP420 in-wall loud-speaker takes the Meridian digital loudspeaker concept and places it into a discreet enclosure, for building into your listening room or home theatre.
