What is YOUR suggestion for the correct wording to use in order to describe undefined speakers you probably won't like?
So many putting words in my mouth. Let me try to clarify. Usually, when I read "revealing" the reviewer treats this without a down side. I'll give you a great, precise example.
The modern Dali speakers have a raised treble profile. That's not opinion, that's measurement, and they treble runs significantly hotter. Now, it would be fine to call it "revealing." In a sense, these are ideal low volume speakers as they will "reveal" more treble ant lower listening levels than another speaker, and if you like that (I do not) then that's a great match. However, if I were to review them I'd put that out there. They are going to be better at low volumes than high volumes, but the average reviewer will just go nuts over the hot treble, say they've never heard such detail in their records, blah blah, without addressing the downside.
Again, these may be ideal for you, your hearing, your paper thin walls, whatever. It is the use of "revealing" to call out something that is not neutral without further explanation.
Best,
E
