Abstract:
1. A sound reproduction system comprising: a loudspeaker enclosure ( processing means for applying respectively to the first loudspeaker and to the second loudspeaker a first electrical signal and a second electrical signal obtained from a same signal by differentiated phase processing varying with frequency, the processing means generating, between the first electrical signal and the second electrical signal a delay varying with frequency and proportional to an acoustic distance between the first half-enclosure, including the first volume, the first loudspeaker and the first port, and the second half-enclosure, including the second volume, the second loudspeaker and the second port, wherein the acoustic distance is larger than a first distance between the first loudspeaker and the second loudspeaker and smaller than a second distance between the first port and the second port over a frequency range from a tuned frequency of the first and second ports to a contribution limit frequency of the first and second loudspeakers.
