Played an outdoor gig last night. It's become an annual event in town (Terre Haute, IN), although it was scaled back this year.
3 bands share one stage and play from 4pm-7pm, 7pm-10pm, then 10pm-midnight. We did this last year with the same closing band, same time slots (we did the 7pm-10pm). This band owns the trailer/stage and PA, so they like to show up early and setup all their stuff before the 1st band. They take up over half the stage. Last year we were cramped for space and their PA was awful.
So this year, I rented my own stage and used my own PA! That's my band's setup on the left (stage right MAINS aren't visible). I overheard some snickering from their PA guys while I was mounting my SLAs.
As you probably expected, they weren't laughing by the end of the night. We had friends and family from the other bands complimenting our sound from those 'tiny' speakers. Their mishmash cabs had tons of farty bass, but the highs were distorted and the phasing was, well just a wonder of physics!
My sub placement was suboptimal, I know. I usually like to stack all 4 in a wedge with a V coupling, but they had to be in front of the stage. Bar owner wasn't happy I brought a 2nd stage, but he got over it.
I think I would need (8) T-39's to keep up with the (4) SLA-PROs. Oh yes, and I ran all this from a 9lb Carvin DCM2004L.
