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


What qualitative or quantitative tests do you think should be performed regularly on all speakers?  
Maybe like “how fatiguing is it with certain gear and cables?”  

Any other ideas?

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. How can they honestly do anything else?

I hadn't heard of this test.  Does anybody perform it in their reviews?
