for music i notice very less bass , (youtube via chromecast or PS4).This is really based on the track of the audio file while i was also noticing in my Sub while playing old songs and new songs .The bass was very smooth in Music and for some songs i need to check if my Sub is ON and working .
The real difference is on the Movies where I can experience the Sub very much and the Bass is very uniform cant identify where it. is coming from FS or Sub.
i find the bass more prominent on games and movies.
