Meridian DSP640

Building on the performance of the DSP520, the DSP640 is designed for the most demanding of listeners. The DSP640 shares the same visual width and sonic character of the DSP520, making them perfect companions in a Meridian Digital Theatre.

In addition to Meridian’s unique Wide Band driver technology, the DSP640 features dual-long throw woofers for extended bass, and dynamic range that is perfect for today’s high-resolution music and movies. All of this adds up to floor-standing loudspeaker performance, without a single inch of floor space.

Why Compromise?

The DSP640 shares the latest technologies from Meridian’s DSP7200 Loudspeaker, including Enhanced Bass Alignment and Centre Elevation, providing incredibly lifelike and spacious sound. This makes the DSP640 a perfect choice for stereo or full surround with virtually no visual impact to the decor. Meridian’s In-wall Loudspeaker range was created to provide no-compromise performance in an environment where floor space is either at a premium, or a conventional loudspeaker is simply not suited.

DSP640, like the entire range of Meridian In-wall Loudspeakers, is built around an aluminum enclosure. This enclosure forms the back of the loudspeaker itself, while the drivers are mounted to another metal extrusion. This provides an extremely stiff “box” and with special dampening material, has no sound of its own to color the music. This makes it ideal for an in-wall loudspeaker. The DSP640 features amplifiers that are optimized for each driver and the frequency range that they are tasked to play. This “active” approach provides the benefits of a loudspeaker with extended bass, and output volume, equivalent to a passive loudspeaker of eight times its physical size. Rather than use a passive crossover that robs the music of resolution and detail, the DSP640 implements this in the digital domain, thereby avoiding any loss to the music. A slender, paintable grill is magnetically attached to the loudspeaker. This allows for the grill to be custom painted or wallpapered to match any décor, while the magnetic mounting system ensures secure grill installation without unsightly hardware.
