Here is my dilemma. I am about 95% sure that I will be installing manifolds (either one or two) on the vertical plane above my TV and main speakers. This area is a vaulted ceiling. I don't have a ton of mounting room in this area but should have sufficient wall for what I am trying to do.
Option 1: One manifold with 4x18's installed on the sides and top/bottom. Possible issues with this is the bottom driver with the basket facing down. How close is acceptable for magnet to attic floor clearance?
Option 2: Two manifolds next to each other with 2x18's installed on the sides. How close is acceptable for clearance of magnets on the baskets that are facing each other?

I don't understand your descriptions
Attic manifolds usually have a bottom opening with drivers on 4 sides or drivers on 2 sides.
What's the top and bottom driver reference?
There needs to be as much space as possible between the rearwave coming off a driver and any fixed surface. No less that 12"-15"

I figured that my description would be difficult to follow, so allow me to illustrate:

I'd go with the dual manifold install spreading the space between them as far as is reasonable given the pitch of the roof.

That's actually not the roof. I have lots of attic space above the peak in the vault. If I go with the dual manifolds, how close together can they be without the backwaves being too close to one another? Two of the baskets/magnets will be facing each other.

How much space can you create between the drivers?

I am in the process of running cable through the attic for my new wiring closet. I'll bring the tape measure up there and get some measurements soon.
