So I am assuming you picked a few points on ceiling that were 45 degrees from MLP and created a circle around those points on the ceiling?
We picked points 45 degrees ahead, behind and also to the left and right , following interpretation of the guidelines,
circles were never mentioned
I suppose the assumption of being equi-distant from the mlp seemed self explanatory and good science. . .
and yes I assume its possible to draw a circle that would include the placement of the tops as a 7 ft sq. with the vertices of that square on the circumference of the circle.
breaking ti down . .
half that square would be a 7 x 7 right triangle. a^2 + b^2 = c^2 - 49 +49 = 98, call C = 9.9 ft.
9.9 / 2 =4.95, which would be the radius, if one were to need to draw a circle wherein the circumference intersected the points that are the corners of the square .
now for SCATMOS, if one were going for all tops equi-distant from 1 central point, a circle makes perfect sense.
I didn't do that but now I lowered my surrounds and mover them forward to about 75-80 degrees, I
I can revisit that geometry .
the sides of the square would put my TM's at a linear 3.5 feet from the mlp, a opposed to the 4.95 for the TF and TR . working as a plane measurement
maybe I can work with settings in the SCATMOS amps and add some delay, or change the distance, and check with a SPL meter ., etc.
break out the tape measure and see how things measure up for keeping good spacing of the TM's relative to the base layer and particularly the surrounds
as my tops are Volt6's, turning a co-axial on its side is not much of a change
I like the "look" of the klipsch SLX as TM's, they tuck up there like it was almost a real plan.
