Hi,
The bass won't matter. These subs use the normal range of human speech with maskeds, and then higher up with ultrasonics.
For best effect, having on either side of your head is preferred. You will only know if they work by testing them with the speaker test mp3 and running an ultrasonic track and listening to hear anything. You should NOT hear anything if the speakers work, and the volume is not set too loud. Use Frequensee, a great phone app to set the volume properly. Don't go higher than -30db at the SOURCE for ultrasonics.
