Thinking about buying these speakers, not sure which ones to buy, they will be used for mobile disco work for up to say 500 people.

What's the benefit of the 1 inch tweeter over the 2 inch tweeter, I know the 2 inch is for longer throw but which one would you use for a mobile disco ??

I will also buy 2 of the ART905AS subs to complement the tops.

Any advice on this would help

thanks
