Maximizing the effect of the
surround soundfield
The listener should not be able to pinpoint the source of surround effects,
therefore output from the surround speakers should not be aimed directly
at the listening area. This is easily accomplished by raising the surround
speakers. Although surround speakers require some reflected sound to be
effective, these reflections should be diffusive — providing randomized
reflections in many directions. Bookcases and other irregular surfaces
provide this sort of diffusion, as do some commercially-available acoustic
panels.
