opus THE HOME THEATRE ENVIRONMENT Front and Effects Channels The front loudspeakers are placed on either side of the television screen, 2 to 3 metres apart. The speakers should be angled slightly so they are aimed towards the listeners. As the rear surround channels are the ‘effects’ channels the reproduced sound should be as room filling as possible.
