ABSTRACT:
The frequency at which standing waves occur in a loudspeaker enclosure may be reduced by the addition of an internal barrier to the enclosure in order to lengthen the effective length of an internal dimension of the enclosure. Additionally, the internal barrier may be configured such that it forms a resistive coupling between two sides of the barrier. By configuring the internal barrier to form a resistive coupling, aberrations in the frequency response of the loudspeaker caused by certain standing waves may be dampened.
