Frequency response in C901 isn't great it's true but there are more important sound output parameters which are really good in C901. Besides frequency response can be improved with manual equalizer settings.

I donīt know how this works, but isnīt there anyone besides SE that can rewrite the frequensy so that will be flat again as it suppose to be from the beginning?
There are no chance to adjust the equalaizer to get the sound right in the menys, the low and high are to far away out of from the eq range.
You will here the lowest bass and highest trebble very loud anyway, atleast with good headphones, itīs annoying to only hear bass and trebble and hardly no vocals.
Wish I had some skills to try to rewrite it, but I havenīt got a clue.
Maybe the first firmware was good, anyone?
Thanks for your help!

Now I managed to go in to an old C702 via A2 uploader and read and saved the acoustic files
The phone still working after my journey in the file system
Making progress

The only thing you can do to improve sound is to put new acoustic drivers on your phone and maybe the 'megabass to clearbass' patch on it. I don't think it's about getting that flat frequency, it's just whatever sound you like the most from putting new acoustics on it. You do that with A2 Uploader...
Acoustics (.wbxml files): ifs/settings/acoustic
Acoustics (.csv files): tpa/preset/acoustic
I hope you find a sound that you like, I would say forget about the flat line frequency graph, that doesn't show much, it depends what type of music you listen to as well, how much bass/vocals/treble you want. Experiment with acoustic drivers to see which you like the most... you will be much happier with sound quality from the blacklizard HD acoustic than the one default in the C901.

Is there no file or something before the acoustic files that make that flat response and character of sound from the beginning?
This is what I thougt: First amplifier, then the file or something that creates that base flat frequency as a plattform, then all the acoustics/equalizer settings that can be custom made in the ifs filesystem! Got it wrong, right?
Maybe itīs like this then: Amp- ifs/settings/acoustics/ and nothing in between?

You're making it more comlicated than it actually is, the sound quality is produced by the files in:
ifs/settings/acoustic and tpa/preset/acoustic
Experiment with those files to find which sound you like the most. Just forget about flat line frequency, the C901 isn't made for that anyway
