Started Djing again do I have enough rig for the gig.

Hi, haven’t DJ’d anything since college when I’d throw dorm parties with an old peavey set of unpowered pa’s and a crown power amp on a desktop. So I booked a summer camp event where they expect 100 people or less. I have a set of Yamaha DBR12’s getting a 3rd as monitors and ekx 18sp. Is that just cutting it or get better tops like elx200 or mackie srt’s. It’s outdoors and people will prolly do alittle karaoke.
