Enhanced Bass Alignment (EBA)
Meridian's innovative Enhanced Bass Alignment (EBA)
technology time-aligns high, mid, and upper bass frequencies
with the low bass, resulting in audibly improved bass transients
and added life and clarity.
Diffraction Expansion Technology
The innovative tweeter design delivers controlled directivity,
wide dispersion, and consistent off-axis response. This means
all listeners get the same experience, turning the listening-
room into one large "sweet-spot". As well as providing greater
freedom of placement due to controlled reduction of unwanted
reflections, this also makes the loudspeaker ideal for larger
areas.
Construction
The DSP730 is designed to have an elegant profile, with only
102mm installation depth.
It is made up of a narrow, 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 first fitted 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. The frame is designed for mounting into
new-build partition and stud style walls, or for retrofitting into
stud or brick/stone-built walls.
A male-to-female IEC mains lead is supplied with the
loudspeaker in order to connect it to the rough-in box, which is
wired to power.
The paintable, perforated steel grille supplied with the
loudspeaker can be fitted where required. The grille is held in
place by powerful rubber-coated magnets which are attached
to the aluminium extrusion that forms the front panel of the
loudspeaker enclosure.
Controlling the loudspeaker
The loudspeaker can be controlled in three ways:
• In most installations, the loudspeaker will be controlled by
another Meridian product within the system.
• Alternatively, the loudspeaker features an infra-red receiver
which allows it to be controlled using a Meridian System
Remote.
• Thirdly, the loudspeaker can be controlled using RS232
commands.
