How it works
- f = /2 × √((/)² + (/)² + (/)²); p ∝ cos(πx/) × cos(πy/) × cos(πz/)

Assumptions and limitations
The model assumes a rectangular room with rigid walls and uniform sound speed. Mode indices set the preview independently of the table filters. Furniture, damping and speaker placement are excluded; this is not a measured response. Example: a 5 × 4 × 2.5 m room at 343 m/s has axial fundamentals 34.3, 42.875 and 68.6 Hz.
