A little tweak to a mobile electric piano brings a better sound to it:
The small loudspeaker got some papercone treatment with thin silicone sealant omitting the dustcap.
One ohm put in line made it sound less aggressive and more pleasing (adding a little bit of current drive to the amplifier)
The sound got much nicer and more articulate!
Disassembling is easy only remove six screws.
loudspeaker is easy removable
And put all back again after tuning / tweaking the electric piano.
Here some fotos of the inside electronics
