Aura A30

Hi Is there any way we could get an firmware update, so we could have higher settings for the treble and midrange, currently they go up to 6 max, A max of 10 would make a big difference, I've tried playing around with the equaliser and I'm just not satisfied with the dialogue in movies and such, just doesn't sound clear, also why is there no option to turn the bass up and down on the subwoofer only or the sound bar only.
