Why are most response charts presented based on power instead of voltage. I thought signal strength at the output of the amp is represented by voltage. In real-world situation, would SPL response not be affected by the impedence curve, increasing SPL as impedence drops (provided current is available) and decreasing SPL as impedence rise? Is response based on watts even meaningful?
