Anyway, the set-up was on an outside deck at a frat house for about 150 people. I spent some time trying to get it all dialed in by ear and finally got it to sound balanced to me. It was a parent’s weekend, so pre-game I played a mix of classic rock and current top 40, but kept it at conversational levels. After the game (Go Gators!), most of the parents left so I finally had the opportunity to stretch it out a bit.
With the gain structure I normally set, I have never had more than one LED light up on the master levels on my mixer. Given the go ahead by “Frat Dad”, I pushed the input sliders up to zero and turned the master to halfway. At this position, I had three LEDs on the master and the second LEDs on the XTIs going steady (I had previously measured 20 volts at 100 Hz and had three steady on the XTI).
All I can say is OMG! At concert level volume, the OT12s sounded incredible with good highs even way off axis and the Titans were producing chest compressing lows that rattled the deck. Clear, loud, and undistorted music across the spectrum. Even thought the system was barely out of idle, I have no idea how much power I was feeding the speakers and without a VM or hard wall limiter I was unwilling to press any further. I cannot, however, imagine needing more (or better) sound that what this set-up produced (and if I do, I’ll build more boxes). Thank you Bill for the opportunity to have an awesome system that even an old guy like me can carry. I still haven’t been able to wipe the grin off my face.
It took three days to figure it all out, but if anyone has a CR-V, I will be happy to share the combination. 
How do you run two OT12's per side? Stacked? How?
