The Festival Where Left and Right Cancelled Each Other Out
Everything measured perfectly in isolation. Left stack: beautiful response. Right stack: equally beautiful. But together? A 20 dB null at 120 Hz that made the headliner's bass drops sound like bass whispers.
The system tech spent three hours checking every crossover point, delay setting, and EQ curve. The answer was simpler than any of them: a single XLR cable with pins 2 and 3 reversed. One cable, out of 200, was wired out of polarity.
SonaVyx's polarity checker would have found it in 10 seconds flat.
The Moral: Always check polarity before you blame the processor, the speakers, or the laws of physics.
