The calculation
Vb = Vas / [(Qtc / Qts)² − 1] Fc = Fs × (Qtc / Qts) A = 1 / Qtc² − 2 F3 = Fc × √[(A + √(A² + 4)) / 2]
Assumptions & limits
A rigid, airtight box with one driver and negligible additional losses. Enter net air volume. Stuffing, leakage, series resistance and excursion limits are not modelled.
