I was reading my Yamaha RX-V661 7.1 manual (Yes, I read manuals) before setting up my HT system. They talked about the presence speakers. They described them as the ones you put above the front Left and Right. The Specs says there 7 channels X 90 watts. but the presence speakers would make 10 including the Sub

On page 12 it shows the setup and includes 10 speakers including the Sub. The specs say there are only 7 amp channels?
What are the Presence speakers driven by and why would I want them? Is it worth spending the extra money to have them on my 7.1 setup? My other AV Reciever a Denon AVR-687 7.1 manual doesn't mention them.
