A new method is introduced for enhancing the low frequency performance of small loudspeakers and headphones. The method overcomes some of the known problems and is able to create a powerful bass enhancement. Dynamics processing is used to maximize the bass output depending on the amount of headroom available in the original signal. This non-linear signal processing creates a series of harmonics. By carefully controlling the harmonics a rich low frequency sound can be created.
