[[File:THX_certified_game_logo.png|thumb|THX Certified Game logo is commonly used on THX-certified video games.]]
THX has created a certification process for additional products including home audio, home theater, video, and automotive sound components and products. THX certification extends to home audio receivers, speakers, desktop systems, [[soundbar]]s, acoustic materials, microphones, and HDMI cables.<ref name="THX_cert_perf_cats">{{cite web|title=THX Certification Performance Categories|url=http://www.thx.com/consumer/home-entertainment/home-theater/thx-certification-performance-categories/|publisher=THX Ltd.|access-date=9 March 2013}}</ref> <!-- NOT TO BE ADDED YET UNTIL A REF IS FOUND - PRELIMINARY CONTENT: "For many years, they also certified various home media releases of movies, games, and other mediums; which is noted by trailers at the beginning (or in the program's later years, after the credits) of each release they certified. However, in late 2012, it was announced that they would cease this certification process for individual releases; with the final release being Lucasfilms' Red Tails in January 2013." -->
