Abstract
In providing stereophonic reproduction of sound in the passenger space of a motor vehicle, a pair of speakers are located at the opposite ends of the dashboard ahead of the driver, one for reproducing the left signal of a sound recording and the other for reproducing the right signal. In addition, at least one of a summation signal made up of the left signal and the right signal is provided from a speaker located at the dashboard between the pair of speakers, and a differential signal, made up of the left signal and the right signal, is directed forwardly from the rear of the passenger space. Further, the differential signal can be made up only of middle and lower frequencies supplied to one rear speaker with another rear speaker turned 90.degree. relative to the one rear speaker and radiating the differential signal to opposite sides of the passenger space. An electronic delay can be incorporated into the rear speakers.
