@thespeakerdude I like your answers about bass helping the entire spectrum of music, yes it is warmer and more tube like, less harsh. Seems to me that the bass being important in the beat is not the reason because even ambiences sound better. Even your last reason that proper bass frequencies give a musical foundation in harmonic ratios doesn't really hold water either because in nature bass notes aren't tuned to the other frequencies in the environment. Could it be that bass simply needs to be in what we hear to make any environment more pleasing, just like the rumble of records makes them sound better. Odd that we strive to make record groves more accurate and 16 ohm speakers take the tube effect of amps away when all the time it is the low frequencies that we enjoy in tube amps and records.
The movie Ford vs Ferrari the engines were "tuned" to match the music and the music was changed in pitch to match the engines in some scenes, it won an Oscar for sound. Think about our happiest times in life, in your Moms arms as a baby, in a safe bed, wrapped in a blanket sitting by a fire, listening to music in a great building. And then think about bad times in your life, school rooms, cheep tinny cars, the screechy voice of your teacher, a cold icy night, hospital rooms all places where there is very little low frequencies and an abundance of high frequencies. Just saying.
