Has Anyone Seen 2.1 Speakers With Bass & Treble Dials ?

Not speaking of tone, but genuine bass & treble dials. It seems that this new gamer crowd is oblivious to them.

Is this a question of how to use bass & treble dials?

Edit: 2.1 speaker with bass & treble dials:

For gaming/movie purpose i would suggetst the new Logitech G51 or the older x540, stay with 2.1 if you listening to music a lot.
