The small, irregular volume of the typical automotive cabin can induce large unpredictable variations in the low frequency response (<200 Hz) of woofers in the audio system. Acoustic transfer function measurements of these effects, made using a reciprocity technique, show these variations at the listener`s position. The response of a subwoofer design at any position in the vehicle can be predicted and optimized through computer aided convolution of the woofer response and the acoustic transfer function. A commercially available loudspeaker acoustic simulator, SPEAK, was used for woofer system design and simulation in an automobile. Application of this technique to woofer system design in large listening environments (home, studio) is also proposed.
