How much do you know about loudspeaker design? Do you have a way to measure the final result? You say you know what you are doing besides the crossover and tweeter, but, no offense, that is like saying you don't know what you are doing at all. Those are crucial components to making a good speaker.
If I were you, I would contact Eminence and ask what would make well with your woofer for your desired application. They have a lot of compression drivers, and I am sure there are a bunch that would work well with that driver for PA applications.
