A four channel quadraphonic diagram showing the usual placement of speakers around the listener. Quadraphonic (or quadrophonic, also called quadrasonic or by the neologism quadio [1] [formed by analogy with "stereo"]) sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space.
The two most common types of speaker enclosure are acoustic suspension (sometimes called pneumatic suspension) and bass reflex.In both cases, the tuning affects the lower end of the driver's response, but above a certain frequency, the driver itself becomes the dominant factor and the size of the enclosure and ports (if any) become irrelevant.
Once designed, the rigging points are hung from the structure, followed by chain motors (or blocks), flying frame and then the speakers. The individual boxes may be connected one at a time or rigged together on the ground and then pulled up. As the array is lifted, individual box angles are adjusted to match the array prediction program.
The "3-2-1 GS" model was introduced in 2003, named for its use of Bose "Gemstones" small speakers, which have two drivers pointing forward and one pointing to the side. [2] [3] The 3-2-1 was replaced by the "321 Series II" in 2004, which included two small speakers and a subwoofer. [4]

Balanced and unbalanced circuits can be interfaced by the use of a balun, often through a DI unit (also called a "DI box" or "direct box"). As a last resort a balanced audio line can be fed into an unbalanced input and vice versa as long as the electronic design used for the output stage is known.
