Box design

Designing an enclosure is a fundamental part of overall loudspeaker design. It's nowhere near as simple as building a "strong, solid box". A speaker box performs a variety of functions and some of them are actually not so obvious.

Take for example: a speaker that's framed in a sealed hollow box, which has nothing but air inside it. What happens? How does it work? Why is the box necessary? Is it necessary?

In order to decide what kind of loudspeaker system you want to build, you'll also need some background knowledge and understanding of how various designs work. Anyway, check out some of my other posts regarding sealed, vented/ported, and labyrinth designs.
