AFI SILVER THEATRE AND CULTURAL CENTER Silver Spring, Maryland
Looking back towards the booth, one can also see the light/sound lock that did not originally exist. This also contributes to the lower seat count than the Silver historically had. Just above the rear surround speakers (this theatre does feature Surround-EX and is THX certified like the other theatres at the AFI/Silver) are the projection/view ports. All five sets of ports are filled with projection equipment.
