Hey community, im a home dj slowly just expanding more of my learning curve and finding out more of the sound industry. Im looking for some good feed back on PA systems. I currently have some really nice KRK rocket 8s and krk s12 subwoofer that are really nice. But now im looking to throw sound harder and farther since there just studio speakers. Music i play is edm. Any suggestions? Aloha
What size of audience are you needed the speakers to cover ?

For home use? Maybe not. 
But seriously, the best way is to try out your sound on a PA and see if it sounds right. If possible, visit a local shop with a showroom or rent a system and throw a test party.
PA rule of thumb:
For every 8"-10" top add a 12"-15" sub below each top. This will do a space of up to 50-100 people comfortably depending on how many combinations.
For every 12"-15" top add a 18" sub below each top. This will do a space of up to 100-500 people comfortably depending on how many combinations.
A single combination is the low number of people, 2 or more is the high number.
And don’t’ use studio monitors like the KRK for PA requirements no matter how good you think they sound. Ever.
The most common error when buying your own PA is buying a set of 15" tops because you think it will give you the most sound for your buck (enough power for a crowd of 200 and enough bass so you don’t need immediately a subwoofer).
Then realizing the mids are ■■■■ on a 15" and it still cannot go that low as a proper dedicated subwoofer.
So I guess my 2 cents is don’t go over 12" for tops and save/spend a bit more for a separate subwoofer WITH A CROSSOVER for tops.
Beware of manufacturers that put some kind of hi/lo filter on the sub but still send a full signal to the tops.
Yep 12" top + 18" sub is the sweet spot
