5 Psycho-Acoustic Bass

The psycho-acoustic bass module simulates deep bass on small speakers by generating harmonics. This improves the bass response on small speakers and also improves power efficiency. The fundamental bass frequencies can be attenuated and removed by the equalizer filters, but the bass is still perceived due to the presence of the harmonics even if the fundamentals are missing. This helps maintain the same level of bass at lower power levels or a higher perceived bass at a given power level, because a loudspeaker is more efficient in generating a high-frequency sound compared to a low-frequency sound.
