I've searched and have been reading several threads concerning the placement of surrounds and heights. I'm trying to decide exactly how to mount these four speakers (gonna use four bipoles) to get the best acoustics in my rather large unfriendly lay out. The speakers will be used in a Great Room (25'X35'X10'), which also opens up to three BRs and a stair case that leads up to the Master BR. I know that this is far from the ideal layout, but it is what it is.
My fronts are Energy C-9s, C-3, and two Acoustic 100 subs (I know weak, but shipping a big/heavy ol' sub to Hawaii costs an arm and a leg).
Heck, HSU won't even ship them to me. I'd be using Audyssey (Onkyo 809) to help with all acoustic problems.
The surrounds and heights need to be mounted "on" ceiling, or on the wall right below the ceiling (about 9'-9.5'). Which would be better? Do the heights or surrounds need to be aimed down or "toed" towards the main listening position if they are bipoles? Should I mount the surrounds (ceiling or wall) 90* or 110* from the main listening position? I could mount the surrounds 90* with the LS about 14' away from center and the RS about 22' away from center. Would that be a lot worse than the other placements?
Sorry for the newb questions. Any help will be truly appreciated.
