full-range sound at an SPL of 105dB at over 9m with bass
extension down to 35Hz. With the latest DSP technologies
from Meridian also on-board, including Enhanced Bass
Alignment, Centre Elevation, Dynamic Bass Protection
and L + R mode, the DSP640.2 is an ideal choice whether

PRODUCT HIGHLIGHTS
Ultra-shallow (100mm deep) box design delivers full DSP loudspeaker performance in-wall, while the rough-in box
and frame system allows for easy installation and precise positioning.
• Audio enhancement technologies built in include
Enhanced Bass Alignment (EBA), FIFO buering, DSP
upsampling, apodising lters, Meridian Centre
Eelevation and Meridian High Resolution (MHR).
• Features 2 x 140mm long throw bass driver and 2 x
85mm wide-range drivers for full-frequency response.
• All-new octo-amp design with Class-D ampliers with
feedback on the output stage which lowers output
impedance and reduces distortion and noise to levels
experienced by only the best Class-AB ampliers.
• Each drive-unit powered by a bridged pair of ampliers;
each pair capable of delivering over 100W into 8 Ohms.
• L + R mode to allow a single speaker to be used on its
own while still reproducing all the audio present in a
stereo recording makes the DSP640.2 a great choice
for use as a soundbar below a screen – especially
when combined with Centre Elevation.

right audio which is ideal for soundbar applications.
• LED indicators show power and standby status in normal use and are also used to conrm conguration settings
during installation.
• All the elements are designed for simple, exible and precise installation into almost any type of wall.
• 100mm mounting depth for easy mounting and installation.
TECHNOLOGIES
ON-BOARD DSP
On-board DSP provides thermal and dynamic bass
protection while retaining very accurate transients,
ensuring that when the loudspeaker is played at high
levels – even over prolonged periods of time – it always
delivers a clean, detailed and accurate sound.
DATASHEET
CENTRE ELEVATION
Meridian’s Centre Elevation technology which is based
on psychoacoustic research raises the perceived image
location from an under-screen loudspeaker so that it
appears to come from the centre of the screen.
ENHANCED BASS ALIGNMENT (EBA)
Meridian’s innovative Enhanced Bass Alignment (EBA)
technology uses two dierent technologies to time-align
high, mid and upper bass frequencies with the low bass,
resulting in audibly improved bass transients and
added life and clarity.
ENHANCEMENT TECHNOLOGIES
Meridian’s unique suite of proprietary technologies
includes FIFO buering, DSP upsampling, apodising
lters and MHR (Meridian High Resolution) to get the
very best performance from all digital sources.

CONSTRUCTION
The DSP640.2 is made up of a slim, self-contained,
all-metal enclosure with a metal mounting frame.
Its purpose-built rough-in wall-box is available separately.
The rough-in box is rst tted to the wall, the frame is
mounted to it and the loudspeaker enclosure is then
bolted to the frame. The rough-in box and frame can
be adjusted for various wall materials and depths.
A male-to-female IEC mains lead is supplied with the
loudspeaker in order to connect it to the powered
rough-in box which is wired to power.
SPECIFICATION
DATASHEET
• The loudspeaker enclosure is tted to its frame
which is designed for mounting into new-build
partition and stud style walls or for retrotting
