WHY THIS IS DIFFERENT
It ranks sub layouts by seat consistency, not by folklore.
The tool screens corners, wall midpoints, quarter-wall and asymmetric layouts against a modal pressure model. The answer is a practical layout shortlist to measure and time-align, not a fake final EQ curve.
Boundary: Pick a layout here, then verify with sweeps and align delay, phase and gain.
