Phase Angle Curve Comparisons and Challenge

[Verdinut]

Here are the Impedance and Phase Angle Curves of a MTM loudspeaker system which I built 5 years ago. The phase angle curve is an ideal one and better than the ones of most commercial speakers even expensive ones. Has anyone ever seen a better curve?
The phase angle curve is the red line:

Impedance compensation was used and proved very effective on the Morel CAW638 woofers:

Here's the chart Ascend published for my Sierras.

As published on the Philharmonic site, this is the Phil 3:

As tested by Shady, this is the BMR:

It's about impossible to tell with a scale of +180 to -180. See my question in the other thread about whether one can change the scale on DATS.

Both curves are pretty good. I figure that Ascend use impedance compensation on the woofers.

Hmmm...this one has a scale of 0 to 20 for magnitude. Your other plot had a scale of 0 to 30.

With DATS, we can select the impedance range to view. It can vary from 0 to 10,000 Ohms.

The magnitude doesn't change the impedance nor the phase angle values. It just permits to include a wider range when needed.
