Sound System under $3000

Dipole - A speaker design that uses two sets of drivers to generate equal amounts of sound both forward and backward, or side to side, with the two sounds being "out of phase." Dipoles are often used as surround speakers, and are very effective at creating a diffuse soundfield when placed on the sides of the listening position. Some speakers offer both dipole and bipole modes.
