You have plenty of choices when it comes to selecting a surround sound system, yet many speakers and receivers fall short in terms of power output and performance. THX believes that having the right components is just half of the equation. The other half is how the components are placed and calibrated, and how room size and acoustics affect performance.
To help match the best speakers and receivers for your listening needs, THX has established certification categories to ensure your home theater system can deliver crisp, clear THX Reference Level sound in the room size you desire.
THX Ultra2 Certified products bring the cinematic experience to larger home theaters, 3,000 cubic feet in size, with a viewing distance of 12 feet or greater from the screen.
THX Select2 Certified products are for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.
Certified Systems (AV Receiver + Speaker Bundle) have the power to fill a small home theater or dorm room where the viewing distance from the screen is 6-8 feet.
THX Certified Multimedia Products are designed and engineered for PC gaming and multimedia on the desktop.
