Various implementations include vehicle audio systems and related control methods. In some particular implementations, an audio system is configured to present audio content to a vehicle occupant to modify the perceived size of the vehicle cabin relative to its actual physical size.

A method to produce a dynamic sound stage for engine harmonic enhancement (EHE). Dynamic refers to the ability to position the sound stage at different positions as the engine operates at various RPMs and load. In order to control the sound stage width, a phase difference can be introduced between a first audio channel (e.g., a left audio channel) and second audio channel (e.g., a right audio channel). In the most general case, the phase difference can be introduced per harmonic per RPM. In this approach, the phase difference can be adjusted such that a vehicle occupant will perceive each harmonic signal to have a particular width. This width can be adjusted independently per RPM regions by tuning the per harmonic phase difference.

A transducer assembly includes a first enclosure element, an electro-acoustic transducer coupled to the first enclosure element, and a second enclosure element. The first enclosure element and the second enclosure element are configured to capture a portion of an automobile frame there between and to define an acoustic volume relative to the automobile frame.
