Excursion of loudspeaker membrane : example
An example of the excursion calculation is shown at the figure below on the left . It is done for the Visaton 170S loudspeaker mounted in the enclosure shown previously.
For the vented enclosure, volume velocities generated by the loudspeaker and the vent are shown at the figure below on the right. This figure clearly shows the role played by the vent which is to compensate a small displacement of the loudspeaker at the resonance frequency.
