So we are a 5 piece band, keys & a guy that can be a 2nd keys or guitar as needed. We have female vox. We have a Mackie 1500 series sub. We run bass, drum kick, keys through the PA with the crossover from the active sub. We are ordering in the next day or 2 as our PA is toast. Not interested in suggestions of other models UNLESS you've A\Bd them vs the JBL PRX line. We want to play some outdoor venues so I was thinking of getting the 15s for more bit more volume but really more long term durability. I keep hearing 15s dont produce as good a mid content as the 12s as a VERY general assumption. They say vocals will be better reproduced by 12s. Personally I'm not a true believer in a 12 sounds like x & 15 sounds like y but... Any truth to that in these particular models?
