DSP3100DS v1.0 200500901 RE
The DSP3100 from Meridian represents
a new benchmark in the development
of compact, high-performance digital
loudspeakers.
Cabinet design
The DSP3100’s distinctive cabinet is
made from braced MDF with piano-
lacquer ends and aluminium side-panels
bonded for rigidity. The DSP3100
offers extremely low coloration, and
this is partially a result of this cabinet
construction. Wood tends to vibrate
at lower frequencies, while aluminium
is very stable; conversely, aluminium
tends to resonate at higher frequencies
while wood does not. Combining the
two by bonding them together as
in the DSP3100 tends to cancel out
vibration across the range. In addition,
the cabinet is further damped with
bitumen, leading to an enclosure that
is exceedingly dead.
The DSP3100 is intended for use
as a bookshelf or stand-mounted
loudspeaker – specially-designed
aluminium stands are available for the
vertical units that can be sand-filled
for maximum stability and minimal
impact on sound quality. In addition,
the vertical units include Omnimount/
universal wall bracket mountings for
additional flexibility in location. The
horizontal centre unit is designed to sit
on a shelf. Feet are fitted to the units.
The speakers are tonally similar to
other Meridian DSP loudspeakers and
as a result they are ideal for use, for
example, as surrounds for a Meridian
DSP-based system. They are equally
suited for use in a smaller stand-alone
system in a study or bedroom, and can
be used as second zone speakers in
a Meridian multi-room environment.
With S/PDIF digital inputs at up to
96kHz, they can also be used as high-
end computer loudspeakers.
The extremely accurate characteristics
of the DSP3100 make them eminently
suitable for studio monitoring
applications, particularly as near-field
or surround monitors in recording and
mastering facilities, where they can
accept digital audio data at standard
digital recording sample rates up to 24-
bit, 96kHz operation.
Inside the DSP3100
Featuring high-efficiency long-throw
6in (160mm) (vertical model) or dual 5
1⁄4 in (120mm) (horizontal model) bass
drivers with doped carbon fibre cones
and cast alloy baskets, the DSP3100 also
includes a very high quality 1in (25mm)
Meridian piston treble drive unit with
doped fabric dome. The drivers are
powered directly by independent high
power, low feedback amplifiers fed
from an audiophile-grade power supply
with a substantial toroidal transformer.
The DSP power in the DSP3100 is
provided by a Motorola 56367 running
at 150MHz, while D/A conversion is
handled by dual 24-bit multi-bit delta-
sigma converters. The vertical units
feature a 2-way rear-ported design
with a single 160mm bass driver, while
the horizontal centre is a 2 1⁄2-way
closed box design featuring twin 5 1⁄4
in (120mm) bass drivers.
The DSP3100 may be controlled and
configured via RS232, and operated by
an infrared remote control unit (not
supplied).
Cosmetic finishes available are black
or silver, matching Meridian’s G Series
components (bead-blasted, chemically
brightened and anodised). Wooden
surfaces are piano-lacquered.
