Sometimes Old Is New (to You)
While looking for something else, I came upon an older article about a copy of a well respected subwoofer by Hsu Research. The project is very straightforward, using sound building techniques, and has clearly copied all the right parts in the right places. It is not hard for someone who is careful, and that is the major reason why it is such a great project.
the subwoofer is doubling as an end table – and fits in well – a major factor for many people as large objects that give no sating can cause problems with the decorator of the house
A project like this one will give you a great sub for your home theater, and will also build your confidence, so that you will then attempt a build of main speakers, or perhaps some other small project, the the assembly of that HTPC.

this is what the raw Sonotube looks like, and don’t fret, it is designed to hold concrete, so the pressure of a vented subwoofer will not be the slightest problem.
the completed subwoofer, looking from the bottom up – by using the floor as a baffle, the frequency cutoff doesn’t have to be as low, or as steep.
This project will give all the bass you will need unless you are a classical fan, and your mainstay is pipe organ recitals Low frequency effects from movie soundtracks will be reproduced with authority – if you’re in an apartment or condo you will be able to get yourself thrown out if you so desire. The barest minimum of tools are all that is required, and if you don’t have them, chances are good you have a buddy who does. As a matter of fact, this makes a good buddy project – you help him build his, and he helps you build yours.
As I said at the beginning, this is from an older article, published in 1999 – fear not, all the necessary items are still available, and the state of the art in inexpensive subs has not changed - besides that, you cannot buy anything pre-made that gets anywhere close for 3 times the price of the raw materials.
This is an audio experimenter’s dream project, which also happens to be an audio gem.
