Meridian Audio has introduced the DSP730, an in-wall digital active loudspeaker that is designed to deliver hi-res audio in small- and medium-sized rooms where performance is paramount. The new loudspeaker joins the DSP750 in the Reference range of Meridian Audio’s Architectural product series.

The DSP730 provides a maximum output of 115 dB at 1m and bass extension down to 38 Hz. According to Meridian, the drive units have been selected to deliver superb off-axis performance, providing wide dispersion for a huge sweet spot and optimal coverage of listening positions. The DSP730 features the same custom beryllium tweeter as the DSP750, which is capable of playing hi-res audio over 40 kHz. The 100mm mid-range driver delivers clear dialog, while the 160mm bass driver produces deep bass frequencies. The three drive units unleash the full potential of the hi-res amplifiers and the Class-M DSP engine, which provides thermal and dynamic bass protection for detailed and accurate sound.

Three bridged pairs of Class-D amplifiers deliver over 100 watts to each drive unit and have been integrated into the design of the loudspeaker, eliminating any need for rack-mounted amplifiers. These amps have been designed to operate comfortably and run perfectly cool, even at the highest listening levels.

As with all Meridian loudspeakers, the DSP730 features Meridian’s Enhanced Bass Alignment (EBA) technology to provide accurate bass alignment. EBA allows the bass to arrive at the listener in time with the higher frequencies, delivering perfectly timed playback.

The DSP730 features Meridan Centre Elevation technology and ‘L+R’ soundbar-mode for TV applications. In the soundbar mode, the loudspeaker plays a balanced mix of left and right audio, while the Centre Elevation technology raises the perceived image location from an under-screen loudspeaker to the center of the screen. The DSP730 can be combined with the Meridian DSW600 in-wall subwoofer to produce a full-range, two-box solution.

For those installs where it’s important to achieve high SPL targets across the entire listening region of large spaces, the DSP730 can be installed in a High Power Array configuration to achieve 122 dB at 1m. By stacking the speakers in this way, there will be no interference or spectral variation between the loudspeakers, resulting in an even response.

This compact loudspeaker, with a mounting depth of just 100mm, features a fully sealed, aluminium acoustic enclosure with double baffle that has been engineered to be rigid and inert. Heavy bracing and FEA-designed acoustic wadding cancels unwanted acoustic behavior, while a separate mid-range driver enclosure prevents interaction with the bass driver.
