Sony SRS-XB43 - frequency response measurements (Patreon)

The Sony SRS-XB43 measures quite natural with some dynamic bass boost for low levels and also some stronger treble boost with peaks at 9 and 11 khz, which makes treble appear quite rough and grainy, especially as there is a strong drop above 11khz which results in lack of details and resolution. I am not sure if the tweeters are doing anything at all. 

Bass reduction at high levels appears more constant and more natural over the entire bass range as opposed to the JBL Xtreme 3 which reduces mid-bass way stronger. But final result still appears to be more convincing from the JBL.
