* Type 1: Small, sealed box — produces tight, focused bass. The most accurate bass response of all box types, but requires more power.
* Type 2: Medium box — comes equipped with pre-cut port hole(s), port hole plug(s), and ports, so it can be used for either sealed or ported applications. More efficient than a sealed box, so you get more bass SPL with a little less accuracy.
* Type 3: Large Box — comes equipped with pre-cut port hole(s), port hole plug(s), and ports, so it can be used for either sealed or ported applications. Much more efficient than a sealed box, so you get more boom for your buck, but with less accuracy.
* Type 4: Bandpass Box — sealed/ported hybrid (a ported chamber houses a woofer that projects into the sealed area). Highly efficient, so you get lots of thump but lose a little accuracy.


How to Calculate Internal Box Volume

* Area (rectangle) = Length x Width
* Area (triangle) = 1/2 Length x Width
* Area (circle) = 3.14 x Radius x Radius
* Area (circle) = .785 x Diameter x Diameter
* Volume (rectangular box) = Area (of one side) x Depth
* Volume (triangular enclosure) = Area (triangle) x Depth
* Volume (cylinder) = Area (circle) x Length
* 1728 Cubic Inches = 1 Cubic Foot
* 28 Liters = 1 Cubic Foot
