The apparent suggestiion that I've never done such a thing is overlooked. ;-)
OK, lets do that::
This is a speaker that has been pointed out as being potentially problematical, but it fails to support the claim.

A comment about the physics of the situation. When a speaker's impedance curve is minimum, the minimum impedance value is usually set by the DC resistance of the voice coil. But the DC resistance being a DC resistance is low on reactance so the phase angle is rapidly decreasing around this point.
Here is the Stereophile review of Thiel 3.7 speakers with a 90 DB efficiency specification.
Thank you for providing more counter-evidence for your as yet unsubstantiated claim about 4 ohm load and 45 degree phase angles. Note that the speaker is more of a resisitve load than most, and it is also highly atypical. Of course there are always a few outlyers, but basing general recommendations on them seems unwise.
That would be yet another undocumented assertion. It only would create an audible situation if it occurred while playing music or drama, which excludes any evidence based on testing with pure sine waves.
BTW the following would be an example of proper evidence for the above claim, but totsa luck finding a power cube for any Emotiva product.
Here is a power cube for a low cost stereo power amplifier - probably not that different from many AVRs:

Thanks again for helping me substantiate my claims.
Congratulations upon piling up such a large stack of unsubstantiated and exceptional claims with so few posts! ;-)
