OK - i read what i could find in section III of the ht faqs/basics document (btw - the dolby link is busted) but i'm still confused. i want to assemble a 5.1 ht system. my first question is, where do the 2 rear speakers go? my second question is, are they referred to as 1)Side Surround speakers (L & R) or 2) Dipole/Bipole/Tripole Surround speakers (L & R) or 3) Monopole Rear Surround speakers (L & R) ? and my third question is - i've got a processor (acurus act-3) which supports front and rear subwoofers. if subwoofer placement critical for best bass, where should they be located? are they best sounding when placed in the corners of the room? thanks for any help!
