Subwoofer Control App: 20–30Hz Level

Created: Jul 17 2018 | Updated: Aug 24 2018

The 20–30Hz Level screen allows you to adjust subwoofer output from -10dB to +10dB in the 20–30Hz range. This control and Anthem Room Correction (ARC) serve similar purposes. Where this control is limited to the 20–30Hz frequency range, ARC adjusts your subwoofer's output across its entire frequency range. 

If not using ARC, this control can be used to modify your subwoofer's response to compensate for the room anomalies or to modify the subwoofers sound to your personal taste. The frequencies adjusted are between 20–30Hz—a range where peaks (room gain) and dips of different amplitudes often develop in listening rooms. The ideal setting is dependent on room size and construction, system configuration, and personal preference. As a rule of thumb, if your low-bass sounds weak, increase this control. If your low-bass sounds bloated, decrease this control.

If using ARC, this control can be used to match your personal taste by further changing the way the subwoofer sounds. 

Note: The 20–30Hz Level setting will not affect the ARC measurements or compensation filters. If you have an ARC correction uploaded to your subwoofer, we recommend first listening with this control set to 0. Remember, this setting will adjust the subwoofer output in addition to ARC's adjustments.

Uncompromising performance. Unflinching accuracy. Unwavering reliability. Harnessing the myriad technical advantages of electrostatic principles to recreate sound in its truest form—this is what MartinLogan is all about.
