摘要： 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.

摘要： A loudspeaker arrangement comprises a mid-range loudspeaker arranged in a dashboard of a vehicle, a first tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle, and a second tweeter arranged adjacent to the mid-range loudspeaker in the dashboard of the vehicle. The mid-range loudspeaker is arranged between the first tweeter and the second tweeter. The mid-range loudspeaker is a non-directional loudspeaker that radiates sound towards a driver's seat and towards a passenger seat in equal parts. The first tweeter is a directional loudspeaker that radiates sound primarily towards the passenger seat, and the second tweeter is a directional loudspeaker that radiates sound primarily towards the driver's seat.
