THX® Certified Program
THX product certification categories are based ondelivering the best cinematic experience to specific room sizes.

• THX Ultra2 Certified - larger home theaters, 3,000 cubic feet in size, with a viewing distance of 12 feet or greater from the screen
• THX Select2 Certified - medium home theater, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen
• THX I/S Plus System - Certified Systems (AV Receiver + Speaker Bundle): powered to fill a small home theater or dorm room where the viewing distance from the screen is 6-8 feet

Accurately translating the cinema experience to the home is not easy. Movies are created in large mixing studios for playback in large, powerful cinema auditoriums. When played back in the home, however, movie soundtracks don’t always deliver the same impact.

With a THX Certified AV receiver, cinema volume and fidelity is recreated in the living room. This performance is achieved through strict laboratory testing, a THX Reference Level design and THX DSP technology.

Performance Benefits
