How to Adjust Bass on Echo Sub Amazon Alexa

The Amazon Echo Sub adds house-thumping bass to recent models of Alexa smart speakers like the Echo Dots 2 and 3, and the Echo 2nd generation tower units.  It also supports stereo pairing of two linked Echo speakers as part of a speaker set that includes the Echo Sub.  Plus, the Alexa app, which you set up this subwoofer through, also features a software equalizer (EQ).  This allows for raising and lowering the Amazon Sub bass output.  With these settings, you can tailor the Amazon Sub bass response to fit your particular listening environment and personal preferences.  So in this piece, we demonstrate how to adjust bass on Echo Sub Alexa speaker.





How to Adjust Bass on Echo Sub via Voice Commands

You can access the Echo Sub’s audio EQ controls by asking Alexa to raise and loser the bass.  Among the three Alexa EQ settings is the Bass control.  Each control has thirteen positions, spanning from -6 to +6 in whole numbers.  To adjust this setting with your voice, speak to any speaker that belongs to the same speaker set of the Echo Sub you wish to adjust.  Say commands like the following examples.  Don’t forget to say your wake word first though.  🙂

To Make the Bass Louder

These Alexa commands boost the Echo Sub bass three positions higher than where it’s currently set.  If the requested setting exceeds the bass control’s highest possible position, then the request sets the control to that highest value possible.

  • Raise bass.
  • Increase bass.
  • Turn up the bass. 

To Set Bass to Maximum

  • Set bass maximum.

To Make the Bass Softer

These voice commands reduce bass volume by three increments. If the requested setting exceeds the bass control’s lowest possible position, then the request sets the control to that minimum value possible.

  • Lower bass.
  • Decrease the bass.
  • reduce the bass.
  • Turn down the bass.

To Set Bass to Lowest Possible Value

  • Set bass minimum.

To Adjust Echo Sub Bass to a Specific Level

You can move the bass control to an absolute level between (-6 and +6) with voice commands like the following.  Again, note that ff the setting specified exceeds the bass control’s highest or lowest possible position, then the request sets the control to that minimum or maximum value possible, depending on the command given.

  • Set bass 0.  Adjusts the bass equalizer control to flat.
  • Set bass +3.  Sets the control three positions higher than its current setting.
  • Set bass -2. Lowers the bass setting three positions under its current position.

You can set the bass level to an absolute value by first setting it to zero, and then issuing another command that sets it to a value between the limits of -6 and +6.

Other Ways to Adjust Echo Sub Bass

The position of the Alexa sub woofer affects how much bass you hear from it as well.





If it’s too loud, try keeping the Amazon Sub low to the floor.  That is, avoid placing it on the same table, at the same level as your the master Echo speaker(s) in the set.  If it’s still too “boomy”, then try putting it behind a couch or a big television.

If it’s too soft, then try moving it up to the same level as the speakers it’s linked with.  Position the sub away from walls, and avoid putting it behind curtains or furniture.  However, if you have no choice but to place it where it is, then you must rely on the built in bass adjustments in the Alexa app to increase bass volume.
