Abstract
Disclosed embodiments include techniques for generating a low-frequency sound field for an audio system. A computing device in the audio system determines that a first playback level of an audio input is less than a maximum playback level of the audio system. Based on the first playback level, the computing device retrieves one or more first parameters associated with a first loudspeaker included in the audio system, where the one or more first parameters decrease a first cutoff frequency of the first loudspeaker to a second cutoff frequency. The computing device modifies a first portion of an audio signal transmitted to the first loudspeaker to decrease the first cutoff frequency to the second cutoff frequency based on the one or more first parameters.
