John, with that description, I would simply then just go with a powered main speaker from Behringer - most of them let you pole mount them or they also lay nicely on their side as a floor monitor type thing. http://www.sweetwater.com/store/detail/B212XL/

But to be honest, spending another 7 bux (though losing the horn) the B250D from Behringer looks like a better deal from a flexibility standpoint.
