cvictorg, and all,
Whoever wrote that "sub primer" is deeply misguided and does not understand how movies are mixed. The following is simply wrong:
"A third sub may be used for the rear surround channels. Many films now have significant low bass in the rear channels. Some processing modes require extra subs for the ultimate experience. Some film lovers feel that having a subwoofer for the rear channel improves impact and realism with such films."
The whole point of the " .1" Low-frequency effects channel used in all cinema systems (mainly Dolby, dts and some Sony) and movie/TV show mixes is for deep bass frequencies below 100 Hz.
