Don't think this is possible, but can I EQ only the headphone jack output of an audio interface?

    Ok, I don't think this is possible, but I'm not entirely sure so I wanted
    to check. I have a Focusrite Scarlett 2i2 audio interface with a pair of
    Yamaha HS7 monitors, but no subwoofer. I do, however, have some older Altec
    Lansing ATP3 computers speakers that do have a sub. Now, I'd like a sub
    with the Yamaha monitor setup, but don't want to drop $450 for the matching
    Yamaha sub lol. So I'm trying to see if it's possible to kind of mix and
    match the two.

    What I'd like to do is to low pass the Altec Lansing speakers so I can get
    just the sub frequencies. There are treble and bass adjustments on the
    Altecs, but turning the treble all the way down isn't quite sufficient
    enough. I initially tried to use the Stereo Mix function in Windows which,
    I think, would allow audio to play from two separate sources (Yamahas
    connected to Focusrite interface as one and Altec speakers connected to
    laptop headphone jack output as the other), this would easily allow me to
    use the EQ APO to eq just the laptop output to the Altecs, but Stereo Mix
    has more or less been done away with. There have been some fixes that have
    worked for other people, but I couldn't get it to work for myself.

    So my other option is to connect the Altecs to the headphone jack output of
    the audio interface. What I'd like to know is if it is possible to EQ just
    the headphone output of the interface. Why I don't think this is possible
    is because the audio path going to the speaker outputs is the same as the
    same as the one going to the headphone output. I'm no where near 100%
    certain of this though, which is why I wanted to check with you because you
    would have a much better understand of this than me.

    Thanks for your help!

      If Configurator utility shows the headphone output as a separate device then just enable it for EqializerAPO and then set the Device: command to use that device.

        It doesn't. :(

    The easiest way to achieve this would be to have an audio interface with more than two output channels, but I guess you want to keep the audio interface.

    The headphone output doesn't need to be accessible separately from the normal audio output of the laptop, as you already have the separation between the Focusrite interface and the laptop output. I think this is the solution that you meant with "Stereo Mix", but such an input is not available with all sound drivers. If you have such an input from the Focusrite, you can redirect the output to the laptop output and apply E-APO processing for that.

    The other way would be to use a software like Voicemeeter, which allows you to specify multiple output devices. To use E-APO on the devices you have to select the MME mode, however, which is not really low latency.
