Subwoofer tuning recommended music (don't use YouTube or other streaming services, the music is compressed and not all frequencies are there!):

1. Robbie Wasserman’s Duet’s (in particular track #6)
2. The 'Sneakers' soundtrack (in particular track #4, suggested by Rel)
3. Otherwise just find a track with a constant deep bass note!
