So a center channel is designed for > people who are sitting off axis and otherwise not needed? in a way, yes. a physical source, i.e. an actual speaker, will always be in the correct place. hence the need for a center in cinema, so that even the people in the cheap seats hear the dialog where the faces are on the screen. a phantom center source, created by sending the same signal to L/R, will eventually collapse into the speaker nearest to you when you sit off-center. as to 4ch surround, it doesn't work that well, as fernando explained. the best proof for this is the total failure of all the 70s quadraphonics standards... what is your intention? from your initial post, it sounded like you want to do away with the center, and do 5.1 playback over a square of speakers? what kind of material do you want to listen to? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
