Abstract
The present disclosure provides methods and systems for homogenizing a low frequency listening experience for users in a plurality of locations, such as a plurality of seat positions in a vehicle. An example audio system includes a plurality of woofers configured to output low frequency sound into a listening environment to yield a homogeneous low frequency sound field. Homogeneity of the low frequency sound field in this case is for example spectrally uniform throughout an extended listening space.
