WebTo use this calculator, we enter a speaker diameter of 4", the Box Volume (0.77 liters), Driver Displacement Volume (0.24 liters), Wood Thickness (3/4" - same as above), and indicate we will be using 3/4" battens. Now it is up to the user to adjust the width, height, and depth of the speaker box until the volume is .77 liters. WebAug 4, 2010 · If you build a box small enough to affect the resonance, then you're going to have problems with the voicing of the midrange. You're better off with a design like Port …
