Hi all...I have the Lexus Premium Audio system in my '15 3IS. Does anyone know what the optimal treble/mid/bass/surround settings are for good overall sound? I found a few threads relating to the ML system but nothing on the standard system. I've tried playing around and it seems like the subwoofer in the car isn't as responsive to lower frequencies as the ML.

Appreciate any feedback. Thanks!

 

Hey, I actually just got my 2015 3IS a couple days ago and have set it up to where I like it. This obviously depends on the type of music you listen to...

Treble +2
Mid -1
Bass +1

I also changed position forward from center 1 bar (+1).

Just for reference, I listen to Acoustic/Alternative, Deep House, R&B, and all types of Rock...even some classical sometimes haha.

 

My settings are close to this, but varied based on the input source. I love the fact that settings are save respective to each input source. Very cool.

Treble: +1
Mid: 0
Bass: +1

 

I listen to BPM and Electric Area...

Treble: +3
Mid: 0
Bass: +2

 

Thanks for your replies! It seems the speed dependent level adjustment influences the settings for some reason but I'm pretty happy with the following settings:

Treble: +2
Mid: +1
Bass: +3
Surround: On
Stage: Middle

 

I'm not a sound guru but try negative instead of positive mid, treble, bass settings.
Mine is :
Treble -2
Mid -3
Bass -2
And I like it .

You will have to turn the volume up with such settings and you can get more details and better soundstage.

 

Interesting. I'll give that a shot.
