Buidling custom loudspeakers is another theme.

Omni

I made this custom aluminum dodecahedron speaker. It uses eleven full-range speaker drivers, each pointed in a different direction. This gives unusually even coverage, so you get a lot more room sound and the resulting reverberation. It's wired so each channel has two parallel sets of three speakers in series, resulting in about 11 ohms. The missing 12th driver was replaced with an 8 Ohm, 100 Watt resistor. Only one of these will be made, and it is "stereo" in the sense that the drivers are vertically split and the ball plays both channels.

The bottom plate has two ports, a 4 pole speakon connector, and the pole mount. The ball is brushed aluminum, CNC plasma cut with a custom Voronoi tessellation pattern, and then TIG welded together.

It is designed for a large interactive sculpture we are building for Burning Man this year, which will benefit from the 360 coverage.
