What tests would you like all speaker reviewers to do for their reviews?

I’d like them to describe their preferred sound types - we all have a preference - up front. Then I’d like them to say how the speaker under test satisfies their preferences. 

The acid test: listen.

BEST TEST OF ALL TIME:

Have the speakers shipped over to me. I will give them a full workup and listen to them and take them apart. The speakers would be sent back with a full report on what needs to be fixed. 

If ALL speakers did this, I bet 99% speakers would not be permitted on the market place as they would fail my examination.

For my ears:
Dynamic compression:  The difference in output at say 70 dB vs. 90.

Distortion at the same.
