AB  - Overall sound quality of factory-delivered automotive sound systems has reached a very high standard. Particularly branded high-end systems comprise great components and are well-tuned. The low frequency reproduction in automotive sound systems is, however, typically flawed. The most prominent flaw consists of resonant bass reproduction and undesirable spectral decay characteristics with strong ringing in wide frequency bands. To overcome this challenge, we adapt an algorithm allowing for simultaneous equalization of multiple channels, assuring full exploitation of the acoustic degrees of freedom inherent to a multichannel system. The sound field can be spatially controlled, yielding a uniform and tight reproduction of low frequencies in all regions of interest throughout the car compartment, with controlled and improved spectral decay characteristics.
