B & W Formation Duo Powered Speakers - Any Good?


My wife has agreed to letting me build a music system for our living room.
She is very picky and will not tolerate a lot of componentry, cables, etc.
I think if it were possible to make the gear invisible she would be OK with that.
Anyway, I've been wondering about the newish B&W Formation Duo speakers.  
Anyone here using them or spent time with them?  They seem to check the boxes of what would work pretty well. 
I like that they can be controlled with a smart phone or tablet and are relatively small.  I do not need to use other sources other than digital.  Room size is about 18' x 12' and don't need to play loud, but I do want good sound.
These cost $4K so let's say my budget is that, assuming you have other suggestions. 
Thanks!

I went to a local shop to hear them.  Didn't like them.  I thought they lacked detail and did not image well.  What do I know?  I've moved on.
Do you know of anyone who can customize the speakers for my ears?
There are few speaker tuners out there. I am one of them. I dont know of any others. The duos are harder to tune as they are not typical speakers. The amp would need to be removed first. 
@kenjit They were not tuned or customized for my ears. Do you know of anyone who can customize the speakers for my ears?
I heard them at Best Buy Magnolia and wasn't too impressed. You should also consider the KEF LS50 Wireless II (with the meta technology) and save a bundle.
I doubt you will get any answers here about these. Nobody has heard them. I have.
