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?
