The THX label has indeed been diluted badly in the home market over time but in it's original state it did at one time represent a well very thought out approach to achieving good home theater sound. THX taught a lot of folks how to better understand bass management, surround sound decoding and speaker technology. As a brand name it's much less relevant now but there was a time when those involved were at the leading edge of developing the best technology and concepts available for recreating theater like sound in a home environment. And Tomlinson Holman has since moved on to do a lot of great work developing other technologies like Audyssey that have had a big impact on the home theater market.

THX is still thing? They only mattered when there were THX theaters; THX for consumers was always a joke.
