extracting enclosure Qb parameter

oldbar · 29th October 2008, 06:25 AM

I was just wondering is this the way to find the true volume of a box you have built.
Also when you have to fill the box for the measurement how full does the box have to be .Does the driver have to be mounted towards the box or inside the box facing outwards

You might want to explain your situation from the beginning rather than from the middle.

Hi,

If its a sealed box and you've measured the driver beforehand :

The change of Fs to Fbox is directly related to Vas and effective Vbox.

You crunch the numbers. The driver should be properly mounted.

Optimum stuffing is when Fbox is minumum.
