Meridian DSP520 Quick Manual

Meridian has introduced a new range
of DSP-based in-wall loudspeakers.
The first to be released is the DSP520
full-range loudspeaker, followed by the
larger DSP640 and a matching sub-
woofer, the DSW500.
Increasingly, home theatre installations
in particular call for in-wall designs,
and Meridian's existing DSP in-
wall model, the DSP420, has been
one of the company's most popular
loudspeaker since its introduction.
The sonic inspiration for the in-walls was
development work on the unique M6
loudspeaker released in early 2012. This
tall, conical loudspeaker features a 140mm
bass driver and an 85mm wide-range driver,
and the same drivers are used in different
combinations in the current in-wall systems,
giving them impressive performance on many

levels, including superior mechanical integrity,
increased bass and reduced upper mid-range
colouration.
The range has been launched with the
DSP520, featuring a single wide-range driver
and single bass driver. The larger DSP640
unit includes dual bass and full-range drivers,
while the DSW500 subwoofer includes twin
bass drivers.
The DSP In-wall range has been developed
specifically to deliver wide dispersion for
maximum listening area, with minimum
unwanted diffraction thanks to careful baffle
and grille design. The on-board DSP provides
thermal and dynamic bass protection with
very accurate transients, ensuring that when
the loudspeaker is played at high levels,
even over prolonged periods of time, the
loudspeakers always deliver a clean, detailed
and accurate sound.
