The band is retooling the PA. In exchange for giving up wedges and buying our own IEMs ( PSM900s) the PA owner is paying for mains. Since he is a big JBL fan (currently using 20 year old 15" passives), I haven't been able to convince him to go to K12s, He will, however go for PRX712s. Regarding subs, this band has never run them (it is a low volume classic country, classic rock band, electric lead, acoustic-electric rhythm, restrained drummer, I've even dropped my volume ) but I've convinced him to go with a sub. Since we are low volume, would the PRX718LF suffice (instead of running 2 subs)? Since the K18 isn't highly regarded, perhaps JBL is the way to go after all?
