[QUOTE="hispls, post: 8855540, member: 614752"] Why would you consider using ports and passive radiator? Just pick one and work with it. Determining passive radiator mass is quite simple. Model your box with port area equal to the piston area of your passive radiator. Determine the volume of that port, then determine the mass of air in that volume. That will be the mass you're aiming to get on your passive radiator. Or you could simply guess and test if you had easily changeable masses and some test tones or tool(s) to measure impedance and just watch where your Z-min lands. [/QUOTE]
