    I'd love to see (hear) it playing... Do you plan any "focusing" of the sound or you leave it omnidirectional ? What about the ozone problem - when y...

    I don't plan on leaving it operating for hours, so I'm not too worried about ozone. I'm going to leave it omnidirectional for the time being, and I'l...
