THX Audio Certification Categories

THX has multiple certification categories based on the room size in which the equipment will be installed. This ensures a THX home theatre system will play loud & clear without audible distortion at THX reference levels in specific room sizes and at specific viewing distances from the screen. This also certifies that the subwoofers will properly pressurize the theatre so that even the most demanding of movie sound effects are heard and felt with visceral clarity. Of all the THX certification standards Ultra2 is the most demanding as Ultra2 systems are designed for a room larger than 85 cubic meters (3000 cubic feet) with viewing distances from the screen greater than 4 meters (12 Feet).
