 I know they are not located by the human brain (my father own a
 professional recording studio and worked for years as a sound technician),
 but the problem I'm thinking about is different: On a lot of setups the
 rear speakers are used to be smaller than the front speakers, so they have
 small woofers inside. For that reason I'm not sure the LFE channel should
 be reproduced by every speaker or just the front ones, or better to ignore
 that channel?
