DSP Settings

Dynaudio engineers have painstakingly created a DSP controller for these speakers that lets you tailor the sound to your particular environment. The DSP settings provide precision adjustments that optimize the speakers for the listening space.

Bass Extension

Low frequencies take an exponentially larger amount of energy to reproduce than high frequencies. That is why the bass extension setting affects how loud the speaker will respond.

At its lowest setting (-10 Hz), the low frequency range is extended by 10Hz. This will also reduce the maximum volume that the speaker can achieve. The default setting of 0 Hz limits the range of low bass while increasing the maximum volume of the loudspeaker. The +10 Hz setting has the least amount of bass extension but the loudest volume possible from the loudspeaker.

  • -10 Hz (greatest low frequency extension, - 5 dB output)
  • 0 Hz
  • +10 Hz (loudest output with least low frequency extension, +5 dB output)

As most professional mixers tend to mix at relatively low volumes (~70-85 dB SPL), the greatest amount of bass extension (-10 Hz) can be used. As you increase the playback volume, you may need to reduce the amount of bass extension in order to prevent overdriving the loudspeaker.

Sound Balance

The sound balance, or tilt filter, represents a refined way to affect the overall tone of the speaker. Depending on the room treatment among other factors, it may be necessary to make the loudspeaker darker or brighter than the normal setting. A dead sounding room with a great deal of treatment might need a brighter setting than a live room with many reflective surfaces.

Sound Balance has three settings:

  • Bright (20 Hz -1,5dB, 20kHz +1,5dB)
  • Neutral
  • Dark (20 Hz +1,5dB, 20 kHz -1,5 dB)

What this filter actually does is tilt the entire spectrum by 1,5 dB at either end using minimal phase or linear phase filters to either brighten or darken the overall response. This minimal filter alters the tonality without inducing audible phase anomalies, thereby maximizing the linearity of the loudspeaker.


If you have positioned your speakers within 50cm of a back wall boundary, the position switch should be placed in the “Wall” setting. This will help with anomalies created by reflections coming off the back wall, especially in the lower frequencies. If your speakers are placed further than 50cm from any wall surface, use the “Free” setting.
