Subwoofer Vent Minimum Port Diameter / Size Calculator

Online calculator helps to calculate the subwoofer vent minimum port diameter or size based on maximum air volume, tuning frequency, number of ports.

Formula :
D = ( 2030 * (V²/F)^1/4 ) / √N

Where,
   V = Maximum Air Volume
   F = Tuning Frequency
   N = Number of Ports

Maximum Air Volume	= Meter³
Tuning Frequency	= Hertz
Number of ports	=
