The gig went off great. Loads of complements about the sound from both bands, and their fans. The new SRX system is awesome now that I have it balanced, and have learned some of it's tonal nuances. It really goes loud, and the single 18" sub's sound more like double 18's I've used in the past.
I set the PA up standard left/right, and because of the room geometry I had the left side turned in about 35 deg with the right side shooting straight out. I put the 15/horn top on the right about 5" higher than the left side. It worked well and there was less comb filtering than previous shows there. It was loud up front with lots of bass, less bass in the back but still sounded good. Vocal clarity was especially good.
