Car interiors are full of materials that obstruct and degrade sound quality. Graphic and parametric EQs are only partial remedies for these problems. In addition, the speakers are not located at equal distances from listeners, creating an unbalanced, uncentred sound stage. Time correction can help fix this, but only for one listening position.
These acoustical problems are so severe that no correction system has been able to overcome them. Until now, claims Alpine. With the introduction of IMPRINT, Alpine provides a hardware/ software combination that not only claims to solve these problems, it actually improves the sound stage, tonal balance and definition — and does it automatically, in a matter of minutes.
