Sound is fifty percent of the entertainment experience. Great sound can really bring out the power of high definition video. And speaker placement is essential to experiencing the true impact of movies, music and games. THX offers speaker set up and positioning tips for 7.1, 5.1 and desktop speaker systems.
A 5.1 surround system has five discrete audio channels: Left, Right, Center, Left Surround, Right Surround and the Subwoofer.
Front Left & Right Speakers (L & R): Place the Front Left and Right speakers at ear height, producing a 45° angle as viewed from the main seating position. This delivers a wide sound stage and precise localization of individual sounds.
Center Channel Speaker (C): Place the Center channel speaker either above or below the TV. Then, aim the speaker either up or down to point directly at the listener. If you have a perforated projection screen, center this speaker both horizontally and vertically behind the screen.
Surround Left & Right Speakers (SL & SR): Place the SL & SR speakers between 90° to 110° to each side and 2 feet or higher above the listener.
Subwoofer (Sub): If you have two Subs, put them in the middle of opposing walls. If you have one, place it in the middle of the front wall.
Desktop System Set Up
Monitor Viewing Distance: There should be a 28 inch viewing distance from your desktop display to your seating position.
Front Speakers: If you have a 5.1 desktop system, the Front Left and Right speakers should be placed to the side of your display, with the Center Channel Speaker either above or below the display —aimed at the listening position.
Surround Speaker Set Up: If you have a 5.1 desktop system, the Surround speakers should be positioned 56 inches from your seating position.
Front Left & Right Speakers (L & R): Place the Front Left and Right speakers at ear height, producing a 45° angle as viewed from the main seating position. This delivers a wide sound stage and precise localization of individual sounds.
Center Channel Speaker (C): Place the Center channel speaker either above or below the TV. Then, aim the speaker either up or down to point directly at the listener. If you have a perforated projection screen, center this speaker both horizontally and vertically behind the screen.
