Why the hell does it matter how far away someone can hear it? Either way, if those are you goals, don't change anything. Because they have nothing to do with how high you meter.
Again... trying to be heard far away, I don't get it. Maybe you just want noise violation tickets? And numbers do not equate to loudness. As KHA has described, his set-up was very very loud, and only metered a 145. Loudness to the ear, and high numbers on the meter, are 2 very different things.
