Abstract
The electro dynamic loudspeaker is often referred to as the weakest link in the audio chain due to low
efficiency and high distortion levels at low frequencies and high diaphragm excursion. Compensating for
loudspeaker non-linearities using feedback or feedforward methods can improve the distortion and enable
radical design changes in the loudspeaker which can lead to efficiency improvements. In combination this
has motivated a revisit of the accelerometer based motional feedback technique. Experimental results on a 8
inch subwoofer show that the total harmonic distortion can be significantly reduced at low frequencies and
large displacements.
