I am acquiring an excelent Sony rack system through co-habintation and
I am wondering what the best setup for the surround sound speakers is.
I am assuming that since the surround volume is labeled "Rear", the 
speakers should be placed behind the listening audience.  My question
is, what is the best placement...high, low, pointing at different angles?
How much do accoustics have to do with these speakers?
Another question I have is, will any type of speaker work as surround
speakers?  I have a set of Bose bookshelf speakers that would have a 
richer sound than the small surround speakers that came with the Sony.
Can/should I use these?  And finally...do all surround systems have 
the logic (?) or decoder for accepting surround broadcasts?

Thanx in advance - If y'all mail me the responses, I'll piece together
a post with the responses!
