The 3TX is designed to be small, light and powerful. The horn is the full width of the box. If you wanted more pattern control you would need a bigger horn and a bigger box, which sort of defeats the whole concept.
Yep. I'm very happy with mine. They fit in the very limited space outside the proscenium at one of my favorite local theaters, where pretty much everybody else has to ground stack on stage. They hide against tent poles at graduations where discreet appearance is paramount. They weigh nothing, and handle immense power. I can live with the pattern, whatever it actually is.
