Due to location, the tonal quality of the perceived sound coming from the side surround speakers is changed in relationship to the sound coming from the front speakers. This is because the outer ear, called the pinna, contours the frequency response of a sound depending upon its direction. The result is two conflicting sound fields - a front and a surround.
THX Timbre Matching technology solves this sound field problem by actually acting as an electronic pinna, restoring and integrating the perceived frequency match between the front and surround speakers. This technology allows you to be placed in the center of the onscreen action with smooth, rich surround sound.
Example: Imagine watching an aviation film with fighters traveling across the room. THX Timbre Matching accurately and smoothly pans the audio from the front speakers to the back speakers, ensuring consistent sound throughout the entire movie.
