Control possibilities

The Dynaudio Sub 250 provides two controls to match the frequency response of the subwoofer and the main speakers perfectly:

•SUB Lowpass: The upper cut-off frequency of the subwoofer, which can be continuously adjusted between 50 and 150 Hz. Above the selected cut-off frequency the sound pressure level decreases rapidly.

•SAT Highpass: The lower cut-off frequency of the main speakers; 60 Hz, 80 Hz or Flat (neutral) can be selected. Below the selected cut-off frequency the sound pressure level decreases rapidly.

Note: The settings for the cross-over frequencies just have an impact on the signal at the SAT/SUB Input! The LFE channel is just used to reproduce very low frequent effect signals. Consequently signals at the SUB I/O - LFE/Slave In are not limited in their frequency response.

General tips

XSUB Lowpass = 80 Hz

The cut-off frequency should be selected as low as possible. Then the subwoofer works without being recognized as a single signal source. Very often a cut-off frequency of 80 Hz has been experienced as an ideal value.

XReduce weak amplifiers and small speakers from bass load

By limiting the reproduction of low frequency at the SAT Output, amplifiers and speakers connected to this output are freed from reproducing the heavy bass load, which negatively impacts the sound quality. This will improve the overall sound of your audio system.

XPlay a music track that has a significant amount of bass over a large bass region. An instrument such as a double-bass or bass-guitar is very suitable. Listen carefully to the bass-line played by the instrument. As it goes up and down in the bass range, the overall bass volume should remain the same – be it with very deep or higher bass notes.

Specific tips

Many processors/receivers provide extensive bass management capabilities to set the cut-off frequencies for both subwoofer and speakers. If using the bass management of the processor/receiver, set the controls of the Sub 250 as followed:

•SUB Lowpass = 150 Hz (at the very right)

•SAT Highpass = Flat
