I have done many high profile hip hop shows.. Wait i shouldnt say hip-hop this is florida and its dirty south. Basically alot of bass - 2-8 of the entourage screaming what what on the mic and the track.
for a 48x24 stage I will use a pair of sb1000's and a kf850 per side for a fill. Always double the wedges - and use 15's if you can find them. Djs need big heavy 15's too - ill use a eaw fr box, jbl sr, or something along that line with a sb1000 per side. It seems like overkill but I *NEVER* get a complaint from these homies.
Most of these types of shows are outside block parties or open air field.. FOH normally 6 850 with a pair of 695 or 750 to handle center/"downfill" 8 dual 18's per side and some earthquakes or sb1000's down the center.
sometimes you shoot yourself in the foot with these type of parties.. they can get down right ignorant and obnoxious around here. To me its not worth the hassels whether its in budget or not - I bring it so *I* dont have to deal with the drama 'yo yo whatsup with the soundman'
