The tweeter is the Meridian 25mm aluminium-dome, silver-wire tweeter used in
all the DSP loudspeakers.
Electronic system
Each speaker incorporates an electronic panel in the rear part of the cabinet.
The speaker accepts digital signals and has two inputs. The input receiver
uses a FIFO (First In First Out) memory buffer for the lowest possible jitter from
almost any source.
Widely acclaimed by audio reviewers, the DSP5000 is unchallenged by any
other system of this size and offers excellent value. It is ideal as a stereo pair, or
linked with others in a surround system.
The crossovers, equalisation, location correction, protection and tone controls
are all implemented in 100MHz Motorola Digital Signal Processors (DSP)
inside each speaker. The DSP feeds carefully tailored individual signals to the
bass, mid and tweeter DACs. DSP5000 uses three Meridian Class-A discrete
75W low-distortion power amplifiers -“ one to power each driver. The electronics
are powered from a high-current toroidal transformer through a custom high-
speed power supply.
Technical Specification
Performance: Frequency response in-room within 3dB from 35Hz to over
20kHz.
Linear-phase mid-“top crossover, 6th-order Linkwitz-Riley
bass-“mid crossover.
Output >108dB spl @ 1m on music material.
Noise less than 15dB spl.
Overall distortion typically <0.02% at any frequency or level.
Inputs: Two digital inputs to SPDIF standard; 32kHz-“96kHz sampling
rates at up to 24 bit; MHR support. (A future software update
will enable support for 192kHz.)
Construction: 2.5-way acoustic reflex system.
2 x 160mm polypropylene bass drivers.
1 x 25mm aluminium-dome tweeter, silver wire, short horn-
loaded with protective grille.
Cabinet constructed in veneered MDF braced and damped, in
black ash, cherry or rosewood finish.
FIFO memory buffer input for the lowest possible jitter from
almost any source.
Four precision 128x oversampling converters for bass, mid
and tweeter signals.
Analogue gain and filtering using proprietary Meridian Class-A
discrete amplification.
Digital and conversion electronics constructed using
advanced surface-mount techniques and partitioned 6-layer
printed-circuit boards.
Three 75W power amplifiers, one for each of the drivers.
Power amplifiers use a unique feedback topology and
precision local error-correction systems to achieve a
performance equivalent to the conversion system.

User tone controls.
Volume and phase control.
Controls: Rear-panel controls for power On/Off.
MSR and RS232 port provide control over bass, treble tilt,
listening axis, volume, time-compensated balance and
absolute phase.
Front display: Eight-character display with system lights, can be blank. DSP5000 DSP Loudspeakers
