Get to know this product.

Offering the same performance as the multi-award winning M6, the DSP520 brings in-wall loudspeaker performance to a new level. Featuring an elegant profile only 8 inches wide, the DPS520 is perfect for delivering high quality music discretely in any room. Integral to the DSP520’s design is Meridian’s Wide Range Driver Technology.  This technology eliminates the traditional crossover between a tweeter and mid-range driver found in every other design and enables the DSP520 to have unmatched mid-range quality especially with voices.
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. 
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.
Meridian Apodising Filter
  • Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.
