Guess you not a star wars fan them!
infact GL founded thx, and no doubt he had a team of people specking it out with him so technically your right but it is his system and I bet the green bucks end up in his account!
But as long as my THX cert system and speakers shake the ground and the sound fill the air with pristine replication of what’s happing on my screen when I watch a movie, what do I care when I'm tucking into the a box of pop corn who actually designed and spec'ed each bit.
Note to self
turn the sound up on the intro to a film with the lion roar as it starts next time next door cat decides to look at the lawn then me with a shady smile with intent on leaving an unwelcomed gift!
