The THX testing process usually begins early in product development. Manufacturers ship samples to the THX Testing Lab in Northern California where a team of expert technicians carefully analyzes each sample and produces reports on their findings. Big reports! They cover hundreds of data points and virtually every aspect of the product’s operational performance.
These findings are then sent to the manufacturer with suggestions for fixing any problems that could prevent certification. In many cases, THX requires the manufacturer to adjust the product’s design or firmware and integrate THX playback features to improve performance and meet the THX spec. Further testing, modifications, tweaks and upgrades are done, and the manufacturer sends back the product for final evaluation.
THX certification is either pass or fail. And product pricing is never a driving factor. If a product meets the THX testing standards, then certification is granted. With all of this testing from THX, the consumer is assured that the TV, receiver or speaker system they are purchasing meets the highest standards for quality and compatibility right out of the box.
