assuming the Alnico magnets are up to full charge, they can be quite efficient. I'd estimate on the order of 95 to 99dB, using today's measurements for efficiency.Your larger problem is that they'll likely need some work to be back up to original spec. While these drivers do age well, you don't know what kind of life they may have led and age does take its toll.
