Unique to every THX Certified Cinema is the THX “baffle wall.” If you were to peel away the screen at any THX Certified Cinema, you will see a large wall of speakers housed in an acoustic baffle. This is called the speaker system enclosure.
The baffle wall is approximately the same size as the screen, providing a solid, smooth uninterrupted surface to distribute sound throughout the auditorium. It produces a large sound image and accurately tracks sound elements with the onscreen action. This makes panning shots and off-screen sounds more believable and natural, helping to pull audiences into the storyline.
