THX Loudness Plus: Loudness Plus improves that Klang of movies at low volume. As soon as a film is played back quieter than the THX reference level, the sound changes for the human ear (less bass, discolored mids, ...) and many of the finer sound effects are simply overheard. THX Loudness Plus fits the dynamics between the front and rear speakers automatically depending on the listening level while correcting the frequency response.
