I just don't get it.
On a 2.0 system all you can have is two channels, nothing more.
The LFE channel from a DVD sound track has extremely low-range frequencies,
that if routed through normal speakers, can cause serious damage.
If you do have a 2.1 speaker set (two satelites and a Bass box), the
case is the same, the amplifier on the Bass Box will route the high-range
frequencies to the satelites and the low-range to the Bass box speaker.
So I simply cannot understand all the fuss!
Sorry! i just wanted to add my 0.02EUR...
