A room resonates at frequencies where sound waves fit exactly between its surfaces. These modes — axial between two walls, tangential among four, oblique among all six — cause the boomy bass and dead spots in small rooms. Even spacing sounds smooth; clustered modes cause problems. Cube-shaped rooms are the worst.

Governing equation

f = \frac{c}{2} (\frac{n _{x}}{5})^{2} + (\frac{n _{y}}{4})^{2} + (\frac{n _{z}}{2.8})^{2}

Reading this result: The lowest mode is 34.3 Hz and 67 modes fall below 200 Hz; aim for even spacing between them to avoid boomy peaks and dead spots.
