" For anyone who never had the opportunity of some school physics experiments: If there is more than one speaker stack in the room reproducing the same signal, it is impossible, due to the physical phenomenon of interference occurring whenever the distance from the listener to each speaker is not identical (ie not on the centre line). See http://en.wikipedia.org/wiki/Interference_%28wave_propagation%29 and specifically the http://en.wikipedia.org/wiki/File:Two_sources_interference.gif there. Also here http://en.wikipedia.org/wiki/Ripple_tank#Interference And even if there is only one speaker stack, reflections from the walls and ceilings will interfere. Walking around the room and listening usually confirms this, and is always worth doing. The only way to avoid interference is to have one speaker in free space, or to have one speaker and 100% absorbent walls. See http://en.wikipedia.org/wiki/Anechoic_chamber This is why rooms often sound better when they are full of people. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
