Without proper acoustic treatment and a sound level meter, you probably will not be able to 'calibrate your speakers', in the sense you presented it. Mixing involves learning about the sound of your monitors and what the results are of mixing on them, then making the necessary adjustments.

Two quick mixing tricks:

1. Test your tentative mixes on everything you can find, including car speakers, boom boxes, cheap computer speakers, home stereo etc.

2. Try, when mixing, reducing the volume to just barely audible. Does any instrument stand out? That may be a problem (even for vocals). Can you hear every instrument? You should be able to.
