There are three performance categories for home theater products—THX Integrated Home Theater Systems, THX Select and Select2, and THX Ultra and Ultra2. THX Select2 is an upgrade to the company’s original THX Select™ Certification for AV receivers. THX Select2 Certified receivers are designed to address the growing needs of the newest generation of home entertainment enthusiasts, those who crave immersive DVD, music and video game experiences, but don’t require the full benefits of a large, dedicated home theater environment. In addition to providing product design and performance specifications to manufacturers, THX Select2 offers additional playback features, including THX Surround EX™ and THX listening modes such as THX Cinema, THX Music and THX Games.
While THX Select2 Certified products are designed for small-to medium-sized residential rooms (2,000 cubic feet in size with 10-foot viewing distances), THX Ultra2 is for the acoustics of larger home theaters. THX Ultra2 Certification is reserved for high-end home theater products, specifically those that have the power to distribute sound to dedicated home theater rooms—3,000 cubic feet or larger with 12-foot viewing distances.
THX Certified Integrated Home Theater Systems are geared to small home theater environments and residential living rooms, a space currently filled by home theater-in-a-box (HTiB) products. Because this THX specification is developed and successfully tested by THX as a system, its components—receiver, speakers and amplifier—are optimized to work together to deliver a THX quality audio experience in an affordable “all-in-one” package.
Each THX certification requires manufacturers to build products that meet or exceed the THX standards for presentation excellence, and include such THX features as Timbre Matching™, Bass Management™ and Re-equalization™ (Re-EQ™). Each THX certification category enables manufacturers to feature popular THX listening modes, which incorporate the company’s proprietary Adaptive Speaker Array (ASA) technology for optimizing playback of multi-channel movies, music, and video games in the home.
