The graph in post #37 shows the 1kHz fundamental level and the levels of the harmonics. The levels of the 2nd and 3rd harmonics are each at about -90dB (0.015%) which is good but the input level is very low at only 10mV.
A linear amplifier is linear if the load impedance does not overload it. A non-linear load has distortion built-into it.
Your two-way woofer-tweeter speaker should have a crossover at the recommended high-cut for the woofer and at the recommended low-cut for the tweeter. Adding a midrange speaker to the crossover messes-up levels and frequencies of all the speakers.
