- Front Left (FL) & Front Right (FR): Position these speakers on either side of your TV or main listening area, facing the listener.
- Center (CEN): Place the center speaker directly above or below your TV, centered with the screen.
- Surround Left (SL) & Surround Right (SR): Position these speakers to the sides or slightly behind your main listening position, facing inwards.
