You could spend a ton of money on fancy products:

Hemisphere from Electrotap
Experimental Meyer Array

or you could follow these instructions to build a cheap array out of IKEA salad bowls and surplus automotive speakers. It won’t sound as “accurate” as those other speakers, but it’s surprisingly good and looks pretty cool on stage.

Special thanks and apologies to Dan Truman and the researchers at CNMAT , who’s scientific work directly inspired this project.

Here is the Make Magazine writeup.

Speakers are Go!

I used an amplifier from Sure Electronics, which I got on ebay.  4×100 watts for $50.  I’m pretty pleased.  I’m using a similar board for my car stereo.

There are some idiosyncrasies that relate to my particular setup, but the math part is adaptable.

This is a UB version. I will not be making a windows version. It is fatally flawed, and will kick your puppy and steal your girl. I probably won’t have time to fix any bugs.
