Use the android app called 'Sound meter' for basic pink noise test tone calibration of speakers. Works great! As for subwoofer level settings, I strongly recommend doing this by ear while listening to music. Preferably something simple like jazz. While listening, the sub should compliment the soundscape......not dominate it. EQ'ing the sub is highly advisable if you can do it to control booming spikes caused by the room. If the sub sounds right with music, it will sound right with movies as well.
