These are arranged in three layers: A middle layer of ten speakers, an upper layer of nine speakers, and a lower layer of three speakers and two sub-woofers. The system was demonstrated at Expo 2005, Aichi, Japan, the NAB Shows 2006 and 2009, Las Vegas, and the IBC trade shows 2006 and 2008, Amsterdam, Netherlands.

Famous quotes containing the words surround and/or sound:
“It is not enough for us to prostrate ourselves under the tree which is Creation, and to contemplate its tremendous branches filled with stars. We have a duty to perform, to work upon the human soul, to defend the mystery against the miracle, to worship the incomprehensible while rejecting the absurd; to accept, in the inexplicable, only what is necessary; to dispel the superstitions that surround religion—to rid God of His Maggots.”
—Victor Hugo (1802–1885)
“The old coat that I wear is Concord; it is my morning robe and study gown, my working dress and suit of ceremony, and my nightgown after all. Cleave to the simplest ever. Home,—home,—home. Cars sound like cares to me.”
—Henry David Thoreau (1817–1862)
