Re: JBL SRX / QSC PL236 underpowered?The more complex stuff you discussed, I would agree with. However, as I've said before the band are just going to use the PA if it's capable and if not, hire a bigger PA. So regardless of calculations, that's what happens. They either have enough SPL and they turn it down to suit or they don't, in which case they hire.
