Subwoofer Control App: Volume

Created: Jul 17 2018 | Updated: Aug 24 2018

Volume: The volume (level) control allows you to adjust the loudness of your subwoofer from -40dB to 12dB. For most applications a setting between -14dB and 0dB is adequate. Setting the level too high will cause the bass to seem bloated and is the most common cause of bad sounding subwoofers. A rule of thumb is that the subwoofer’s bass should not draw attention to itself. Instead it should simply make the system’s low end seem more extended and accurate.

Sweep: The Sweep feature is useful for locating areas in your listening room where troublesome rattles or resonances may occur. The tone sweep feature may also prove useful when setting phase, crossover, and volume on the subwoofer. Pressing the Sweep toggle initiates a repeating tone sweep from 20–120Hz. Volume can be adjust while the tone sweep is playing. Pressing the pause button pauses the subwoofer at a specific tone frequency and also allows you to set a specific tone frequency. While a tone frequency is paused, you can select 'Continue' to adjust the level of the subwoofer. The tone sweep will continue until the Sweep toggle is set to off.
