Again, I truly appreciate all the help.
The Bi-Amp just adds more complexity to the situation.
If I let Audyssey find the Heresy's by measuring them as Surround-Back along with the 5.1, but leaving the Heresy's in the Front-B position, it will find them and measure them and know where they are at.
My last clue for today. So, Audyssey will not treat the Heresy's as separate speakers becasue with this configuration it will regard them as a part of the bi-amping scheme, or in otherwords it will ping them together with the Front LRs of your 5.1 setup. Even though physically you will have 5.1 + 2 = 7 speakers + 1 sub in your system, Audyssey will only do the setup for 5 instances on speakers plus 1 more for sub. Try it please and report back.
Otherwise, I agree with Jerry to AskAudyssey!
