There are formulas to calculate the resistance porosity of the material and the thickness of the material needed for membrane construction. An aperiodic port design is basically a leaky sealed cabinet which uses ports filled with foam that allows better bass response from a smaller cabinet compared to a sealed design but without the impedance peaks typical of a ported design. Loudspeaker Design Cookbook by Vance Dickason uses a lot of measurement and modeling to show the Variovent equates to stuffing a sealed box. Need to re-measure though and was wondering if aperiodic would work.
