Learn How to Calculate Subwoofer Enclosure Tuning Frequency - Tutorial

Definition

Subwoofer box tuning frequency is determined by the co-ordination of air compliance, box 's volume and speaker resonance frequency.and the tuning changes the frequency at which frequency response peaks.

Example

A subwoofer box of volume 400 m³ requires the minimum air of 100 m³. Resonance frequency of speaker is 40 hertz. Calculate the tuning frequency (F_b)?

Given,

To Find,

Box / Enclosure Tuning Frequency (F_b)

Solution

F_b= (A / V)^0.31 x F_s = (100 / 400)^0.31 x 40 = 0.6507 x 40 = 26.028
