Anyone Build Their Own Sub-Kick?

Well? What did you use? How did it turn out? Details, details. I'm building my own, and want to avoid some pitfalls. So any guidance or advice is greatly appreciated.

Ranjam, you really don't have to go to that much trouble. If you have an old stereo speaker lying around with a decent-sized woofer, simply wire the speaker's input to a low-Z input on your mixer or card. If you're using 1/4" jacks only, it's a direct connection. If you have to convert from 2-wire to XLR balanced, here's a link to help you:

If your speaker uses bare wire inputs, just ignore the plug in the diagram and observe polarity. You'll probably have to seriously crank the input gain to get a usable signal.

Too late, Steve. Bad things usually happen when I am bored and have time on my hands. But this turned out pretty cool. I basically used 'stuff' I had laying about, and spent a grand total of $6 for a mesh head. I knocked the air vent out of an 8" tom I had doing nothing, and put in a 1/4" jack. I know I coulda/shoulda/woulda used an XLR, but I didn't have one, and I saved time not making the air vent hole a whole bigger. They seem to start out as 3/8" to begin with, which is perfect for a 1/4" jack. I did have the jack with a longer than usual thread, which is what you need.


After taking the original batter head off, I put the 8" rubber-surround woofer on top of the shell, and put the rim back on, with a Pearl mesh head (just for protecting the speaker).


And I wired the speaker up. Simple.


I took a chopped down mic stand that I was using for micing guitar cabinets, and the tom fit quite nicely on top, once I used a memory lock to prop it up. Done. It works tickety-boo. But I am lazy by nature, so I didn't want to waste a day doing this if it was more trouble than it's worth. Oh, and 'instructables' has the greatest non-porn web site ever ;). Also gearslutz has a few threads on this idea. Many people say you need a pad because the signal is actually hot enough to clip your preamp. Someone built a pad inside the tom shell, but I use a DI box that already has selectable pads, so this project is done (impedance matching and padding done without any work or extra $$$ involved). And working quite well. I paniced for nothing, and made you give me some answers that I ignored and jumped right into the deep end. I apologize for that.
