With the speaker layout as described you won't get anything close to third order. In particular in the horizontal plane you will get a performance that is maybe a bit better than first order, but not much. Any decoder designed for that layout will just have to ignore most of the higher order information, or produce severe spatial aliasing if it doesn't. In that case all sound will be pulled towards the speakers, with moving sources appearing to jump between them. A good layout for 3rd order would be 8 speakers in the horizontal plane, 6 each in two rings at +/- 40 degrees of elevation, and one top and bottom, for a total of 22 plus any subs. So the first thing I'd do is to revise this layout. Also with the relative small size (5 m diameter) any use of directional speakers (like horns) would be a bad idea. We can discuss this off-list if you're interested.
