Speaker quality question YPG-635

[Christian5]

Hello, I want to know the quality of my speakers in my YPG-635. I have been playing it at just over 3/4 of the total volume, but never at max. Say a 7 or 8 out of ten on a normal volume dail, but never any higher than that. Do I have to worry about damaging my YPG-635's speakers playing it at that volume all the time? And remember that the songs and styles sound a lot louder and have a lot more base than playing the keys. I would think that it would be designed the so that the amps would not over power the speakers and cause damage to the speakers over a period of time. Can I keep using my 900 dollar keyboard at a 7 or 8 volume without having to worry about damaging or loosing any quality from the speakers over a long period of time? Thank you so much this has been bothering me for a while and I can't find any info on the web.
