I'm going to be buying an AV Receiver soon and some speakers + subwoofer. I'm just wondering though, how far up and across should speakers be situated? Is it ideal to have 1 speaker in each corner of the room and the centres' dead centre. OR, should they be situated in proportion to the "normal" listening position of the person watching the movie? I'm thinking that I can put 1 speak in each corner of the room and then adjust the sound level via windows so that if the speakers to the left are further away, they can actually be louder to compensate for this. Also, should they be below or above ear height? My setup will be for Stereo (Music) and DTS/Dolby (Movies) so I'd like the best overall setup. Vielen Dank, Phil.
