There are two areas that you can play with. Although they do not adjust the treble per say the end result by adjusting the bass would benefit your overall experience. Entering the distance of sound bar & woofer as requested in setting is important. I also found woofer location is equally paramount in determining the final outcome of higher quality sound. I have tested different methods of placement, and came away with a final decision to have them facing me from the corners of my room. Remember corner placements enhence bass production. The worse is around your chair facing the TV as low frequency is somewhat out of phase. Also under speaker setting there is an individual adjustments for sound bar and sub woofer volume. Play with different minus or plus dB ratio to achieve an immersive balanced sound from left & right channel. When you are finished with this adjustments you can start listening to your music and performs individual bass adjustments on different songs through SW+/- switch on remote. Hope these help.
