Need speakers that can rock with just one watt? You found da place.

RE: What do you make of this? (Impedance curves)

the cabinet type and woofer/subwoofer characteristics need to be stated. the rise at 20Hz could be the lower impedance peak of a large vented cabinet with low Fs woofer tuned a bit "high" (~32Hz) - if so, Z should drop towards Re as it goes down below 20Hz.

A 10 ohm resistor could be compared with the meter at each frequency of interest to correct any non linearity in the meter and allow even cheap meters to work. Just adjust so it reads "10" with the resistor in place, then measure the speaker. Something is flattening or appearing to flatten out the impedance. It takes a function meter or sine generator with fine increments to do it by "hand".
