You just can't reproduce sounds from behind you with
speakers in front of you. It's impossible.

This is not entirely true, actually the ears works as a filter, so that
sounds comming from behind will have a dramatic drop in the 8 kHz area. This
means that if you cut the 8kHz area from a sound image, it will appear as
the sound is comming from behind.
