Laserdisc - Star Wars '97 AC-3 THX Sound System format 42/43 special modifications myself

THX eXperimenting with use of the baby boom on Lc Rc as well as new surround positioning placement and few other special modifications I made myself. Surround sub bass extension that enhances just the surround channel with two large JBL TCB subs front and back of the room. These subs can be mixed or matched with LFE.1 or sub bass extension with JBL 4645/C subs. Up to x6 subs running or if I change the formatting I can run the subs on Lc Rc as well total of x8 subs for Star Wars. The sound is better with a five screen much better sound definition behind the screen with Star Wars at this JBL Lucasfilm Ltd THX Sound System home cinema that uses the original professional commercial THX.
