A:AnswerThere is no way to control just the bass on this unit. You can adjust the volume with the “puck,” but nothing else can be adjusted. You may be able to change the bass a little by going into your speaker mixer through the computer screen, but that is the only way that you may be able to change it.
A:AnswerInteresting question. I have a sound blaster external sound card. I have so many ways to produce more watts with it, it is difficult to answer scientifically, but without boosting all the tweaks to get more volume, I run at between 10-30%. Some recordings or audio situation require more volume and it's there if needed. The amount of sound is not the issue with those speakers
