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.
