There is a discrepancy in the 12pi impedance measurements of 2005 and 2006. 2006 shows a normal impedance of about 4ohms and in 2005 it's lower. So when it comes to choosing an amplifier, what is the normal impedance of a single 12pi?

In 2005, I measured slightly less than 3Ω Zmin, and in 2006, David measured slightly higher than 3Ω Zmin. I suspect the difference is probably due to line length. We considered line impedance to be negligible and didn't bother to measure it at either event.
