New Shapes for Speakers

  Speakers have always been round in shape. What if we explore Mono or Stereo sound speakers in different shapes live pyramids, triangles, squares, cubes, and see what sound enhancements we can come up with.
  I think that if it were a two or three dimensional shape rather than cicular we can develope a completely different sound set-up like enhanced surround sound or tweeters or woofers or midrange for any sound system.
