This system is using twice as much power and has additional upward facing tweeters. But a lot of the extra audio performance may be from driver enhancements, Smart Amp Technology and Dolby Atmos processing.
If a Windows user could turn off all the extra software and driver enhancements that would give a comparable audio quality to a default Linux installation with no processing
Considering the small size of the laptop speakers you need more than just an equalizer
I suggest you replace pulseaudio-equalizer-ladspa with Viper4Linux
maybe there is a specific driver for my speakers ?
There are no alternative drivers for this device
Headphones and speakers use a shared output device on the ALC285 audio codec
using the ‘snd_hda_intel’ driver

With only one analog audio device for playback there is no option to separate audio outputs for headphones and speakers
The main factor causing a difference in audio quality is the audio transducer converting electronic analog audio to audible sound
