At a Glance
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.

Wide Range Driver

Loudspeakers use crossovers to “divide” music into bands their drivers can reproduce. This introduces distortion, reducing sound quality – particularly on human voice recordings. Designing a single driver for both mid and high frequencies made a crossover within the vocal range unnecessary, avoiding distortion and reproducing more lifelike vocals at all volume levels.


Traditional audio systems often require large, expensive cables to maintain their performance. Meridian's SpeakerLink uses an “Ethernet style” cable that delivers pristine digital sound and control down a single cable between Meridian components. The result is simple, unobtrusive, and cost-effective cables that are easy to install.

DSP Loudspeakers

The traditional setup – amplifiers driving passive loudspeakers – is inefficient, limiting sound quality. Meridian loudspeakers contain a complete, matched audio system with efficient DSP crossovers, multiple DACs and driver-specific amplifiers, giving higher overall quality, less power use, and the performance of a traditional loudspeaker eight times the physical volume.

Enhanced Bass Alignment (EBA)

In a large loudspeaker, low frequencies (bass) play slightly later than midrange and high frequencies. This “smears” the sound and reduces music’s sense of space and realism. Meridian DSP technology adds fractional time delays to the mid and high frequencies in the loudspeaker. Thus all frequencies play in perfect time with one another, for significantly increased realism and enhanced bass transient response.
