Could an option to equalise sub-bass range of around 20Hz to 60Hz be added ? I like my car to shake when I play hip-hop, but the current Spotify options don’t allow me to equalise frequencies that low. This would certainly set out Spotify from other companies who don’t currently have the option either. Also, being able to change all frequencies with a greater range would be huge. It’s my understanding the peak amplitude of a song isn’t always the same as what the iPhone/Spotify/earphones etc is limited to. So being able to raise the track volume instead of just the system volume is another way to improve the equaliser settings.
