Batboard

I have some room behind the grill of my truck, so all of these speakers are an option. (although I probably can only fit one!) so all things considered which of the above would be my best choice? Obviously the BP100 is the most expensive... but I have heard many say that they like the sound of an Atlas Style speaker the best.

Keep in mind, I will be using it as a PA quite a bit - what would you choose?
