Kensington GR questions

[BeerCan]

Now that I have decided on speakers for my upstairs (Focal Electra) I am starting my pursuit of my main living area speaker.

One speaker high on the list is the Kensigton GR and I had a couple of questions from current owners.

How do they sound off axis? Listening in this room is rarely done in one spot due to different activities that may be going on

How much do the covers affect the sound? My wife does not like the look of plain drivers.

(don't kill me) How do they sound with normal TV/Movies, not the earth shaking bass stuff but normal dialog?

Does the walnut seem to darken with age?

I am trying hard to find a place to demo these but this particular speaker is very hard to find in my area.
