An audio system for a vehicle has at least one source of audio signals. At least one array of speaker elements is located at each seat position that radiates within a range of bass frequencies. For each at least one array, the speaker elements receive a common audio signal, and a respective filter is disposed between the common audio signal and each of the speaker elements. Each respective filter processes magnitude and phase of the common audio signal independently of each other respective filter to thereby define a directional audio radiation from the at least one array.
