I've been looking into ambisonics and that's actually what i was thinking of in this 4 channel set up. It sounds difficult to set up and will take a lot of learning. Regarding the speakers: Actually, they are fairly cheap as far as higher end speakers go. I like them quite a lot given their price/performance point. It sounds like i'd do fine with 4 channels in a small space even when playing back hollywood surround sound material. > ------------------------------------------------------------------------ > > _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user@xxxxxxxxxxxxxxxxxxxx > http://lists.linuxaudio.org/listinfo/linux-audio-user > _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
