Editing 10.2 surround sound (section)

===12.2===
The only addition with 12.2 from 10.2 are the "point surround" or "diffuse surround" channels. These would be placed at the same angles as the standard surround speakers at +/-120 degrees, but would be diffuse radiators using [[dipole speakers]]. They would emit sound to reflect off the walls before arriving at the listening area.<ref name="tonmeister1"/>
The 14 discrete channels are:
[[Image:sound-10 2.svg|thumb|right|300px|Setup with point surround channels]]
*Five front speakers: Left Wide, Left, Center, Right and Right Wide
*Five surround channels: Left Surround Diffuse, Left Surround Direct, Back Surround, Right Surround Diffuse and Right Surround Direct
*Two LFE channels: LFE Left, LFE Right
*Two Height channels: Left Height, Right Height

The ''.2'' of the 10.2 refers to the addition of a second subwoofer.  The system is bass managed such that all the speakers on the left side use the left sub and all the speakers on the right use the right sub.  The Center and Back Surround speakers are split among the two subs.  The two subs also serve as two discrete [[Low-frequency effects|LFE]] (Low Frequency Effects) channels.
