hello, after doing the typical usb fix I did a swap of the 2 internal loudspeakers. I took 2 loudspeakers from a 5800 and put it in the n900 body. 1 on them fits perfect, the other one ( near the camera ) needs some mods to fit well. also 5800 are bigger than original ones, so they don't contact well with the mainboard. the "problem" starts here... I soldered them ( 5800 ) to the mainboard and switched ON the phone. wow they sound louder. I played music at maximum level and output level is higher but sound is too sharp. any ideas? what can i do to make sound less sharp?? just for trying I took 2 big loudspeakers ( 3W input ) and just can say...wow... playing a movie with that speakers in a phone is a nice experience. regards
