How to Adjust Bass on Echo Sub

The Echo Sub adds house-thumping bass to recent models of Alexa smart speakers. It also supports stereo pairing of two linked Echo speakers as part of a speaker set. 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

In summary: You can access the Echo Sub’s audio EQ controls by asking Alexa to raise and loser the bass. Among the three settings is the Bass control. Additionally, each control has thirteen positions, spanning from -6 to +6 in whole numbers.  You can adjust this setting with your voice. To do that, speak to any speaker that belongs to the same set as your Echo Sub.  Say commands like the following.  Now 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. Now the setting you request may be higher than the bass control’s highest possible position. Then in that situation, 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. Now the setting  you ask for may be lower than the bass control’s lowest position. Then in that case, your request sets the control to that minimum value.

    • 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.  Now the setting you set could exceed the bass control’s highest or lowest position. Then in that case, the request sets the control to that minimum or maximum value possible for it.

    • 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 issue another command that sets it to between  -6 and +6.

You can also adjust the bass from the Echo Sub via the Alexa app.  Follow these directions to do that.  Note that there’s a slight delay between the time you move the slider control below, and when the bass changes.  However this lag usually lasts less than a second.

Other Ways to Adjust Echo Sub Bass

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





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

If it’s too soft, then try moving it up to the same level as the master speakers.  Furthermore, position the sub away from walls. Also, avoid putting it behind curtains or furniture. Now perhaps you have no choice in the placement. So in that case, you must rely on the controls in the Alexa app to boost the bass.
