DSP730
IN-WALL DIGITAL ACTIVE
LOUDSPEAKER
OVERVIEW
The DSP730 architectural loudspeaker combines incredible performance with a compact design. Designed for easy installation and outstanding performance, the DSP730 delivers a maximum output of 115dB@1m and bass extension down to 38Hz. When three loudspeakers are used in a High Power Array, the result is full-range sound at an SPL of 122 dB@1m.
Its array of drive units includes a high-performance beryllium tweeter for ultimate Hi-Res fidelity. Capable of playing over 40kHz, the DSP730 has superb off-axis performance enabling it to produce a uniform and lifelike stereo image over a wide listening area.
The sealed aluminium cabinet design ensures that a reliable and repeatable performance is achieved regardless of the installation.
High dynamic range, low distortion and an outstanding signal-tonoise ratio combine to provide high-quality sound with exceptional headroom and low-listener fatigue in any room.
The DSP730 can be combined with the Meridian DSW600 in-wall subwoofer to produce a full-range, two-box solution.

PRODUCT HIGHLIGHTS
Ultra-shallow (100mm deep) design provides full DSP loudspeaker performance, while the rough-in box and frame system allows for easy installation and precise positioning.
•
•
Three new, high-performance drive-units.
‘Double-baffle’ aluminium enclosure design minimises unwanted resonances and colouration.
• Separate mid-range driver enclosure eliminates
• interaction with the bass driver.
Grille attached by magnets may be painted to match interiors.
• Each of the three drive-units powered by a bridged pair of amplifiers; each pair capable of delivering
• over 100W into 8 Ohms.
EBA (Enhanced Bass Alignment) eliminates timesmearing across the frequency range.
• Dynamic bass protection provides maximum excursion without distortion.

USER FEATURES
• The front of the loudspeaker carries the on/off rocker switch, an infra-red receptor window, an RS232 socket and a three-way channel selector rocker switch. When switched to L + R, the loudspeaker plays a balanced mix of left and right audio which is ideal for soundbar applications - especially when combined with Centre Elevation.
• LED indicators show power and standby status in normal use and are also used to confirm configuration settings during installation.
• All the elements are designed for simple, flexible and precise installation into almost any type of wall.
• 100mm mounting depth for easy mounting and installation.
TECHNOLOGIES
CLASS-M DSP ENGINE
Phase-linear DSP crossovers with text-book performance ensure the drive-units remain in phase with each other across their crossover regions. The DSP engine also 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.
MERIDIAN DYNAMIC AMPLIFIER DESIGN
Hi-Res power amplifiers include feedback from the loudspeaker terminals on the output inductor which lowers the output impedance to levels rivalling good Class-AB designs, for perfect cone control and maximum detail.
ENHANCEMENT TECHNOLOGIES
Meridian’s unique suite of proprietary technologies includes
FIFO buffering, DSP upsampling, apodising filters and
MHR (Meridian High Resolution) to get the very best performance from all digital sources.
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.
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 time-aligns high, mid and upper bass frequencies with the low bass, resulting in audibly improved bass transients and added life and clarity.

CONSTRUCTION
The DSP730 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 first fitted to the wall and wired to the mains supply. The frame is then fitted 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 loudspeaker enclosure is fitted to its frame which is designed for mounting into new-build partition and stud style walls, or for retrofitting into stud or brick/stone-built walls.
• 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.
