Wav file distorted on one proffie board but not another

Proffieboards
1

Hello, first post but I’ve been unable to find someone with a similar issue.

I have a Sabertrio (S3) proffie 3.9 setup that uses their unique “audio chip” style speakers.

I also have an LGT proffie 2.2 saber from AliExpress that uses what I believe to be a 24mm speaker.

Long story short, when playing a .wav audio track, it’s sounds much more distorted and blown out sounding on the 28mm S3 install than the LGT. This is with identical frequency cutoffs in the configs.

Both use speakers from S.O. Although, the S3 sounds bad (the same) across two separate audio chips. (Stock and S.O elite)

Is this just me being misguided thinking a larger speaker would be better in every way when it’s actually worse in some areas or is this an issue that is due to S3 and their unique config/proffie os version?

There are a lot of possible reasons for this, like:

  • blown speaker
  • dust or metal bits in the speaker
  • bad battery
  • damaged amplifier
  • bad sd card
  • volume too high
  • software bugs
  • shorts
  • loose speaker
  • bad speaker connection

Things would need to be swapped around a bit and reprogrammed to figure out exactly which components are causing the problem. Prime suspects are of course the actual speakers, but it could definitely be something else.

Thanks for the response.

Since it happens across two separate speakers and 3 different batteries I’m going to assume it’s something to do with the amp on the board.

Especially since I can hear a hissing/white noise in one of the tracks I play, maybe the gain is too high or something. That’s my guess anyway

Also, is there a way to cut off high frequencies like there is low?

There is no “gain” on a Proffieboard, because it’s a purely digital amplifier.
Hissing and white noise can still happen for various reasons, the most common one is that the 5 volt input isn’t stable, which means that the booster that produces the 5 volts isn’t working properly.
