In the past, sound effects were extracted
from a sound matrix embedded into the front channels
but the newer Dolby Digital standard common in home
theaters already contains a dedicated track
with rear channel effects on your DVD's.

Unlike your front channel loudspeakers, they need not
be positioned to form a stereo triangle with the listener
but can be positioned to radiate indirectly.
This results in a diffuse soundfield.

To build these speakers, simply build an extra stereo pair
of your front stereo speakers and position them behind
your viewing position.

In a perfect world, you should have identical speakers
in your home theater setup -- but what if you're
on a tight budget?

of rear speakers for almost peanuts.
