That's exactly what I'm saying..most people don't try customizing their setups to the point where they're building 100% custom boxes, and therefore most people don't have 12s playing at frequenciesAs far as most people that have 12's that want play low its due to them using prefab boxes, sealed, or have a high tuning for burp purposes.. Not trying to be a prick just telling the truth..
And to be honest, I disagree when you say brand doesn't matter..a sony x-plod isn't going to hit as hard as a SKAR in the same box.
