Couple thoughts..........
What kind of events are you doing DJ music for weddings ect where some people
do not want to be sitting in full party volume music all nigh or are your events full on dance partys, Rave, EDM
where everyone there is there to party?
If there are your wedding or corporate type events have a party zone set up for the dance floor
and then as suggested set up some smaller delay fill speakers help cover deeper into the room.
In the fill speaker zone have the music level much lower but have your announce mic and any mics
used for the toasting, presentation ect. turned up higher in the fills.
That way the announcements can heard when needed but the party volume stays on the dance floor,
