F7 ?speakers

First Watt f7 owners, what would be a good speaker for the amp? I’m looking for a full range. They have to be in a niche about 6’10” long, 2’ deep. The room itself is 14x12’.
Now I’m using Fritz Carbon 7, to which is added audio smiles super Twitter. It’s great, but could be better. 
So far, Tekton is one of the most interesting choices . I wonder which model-Double Impact
or Electron? 
I think Cornwalls are too big and will be very close apart. 
My other system is full range 8”” driver by Louise from Omega speakers and small Kitoki (Wolf’s ear Audio, Canada) amp, so I’m not interested in single driver speakers for this system, I want to enjoy both worlds. 
On the other hand, I heard that PS Audio is releasing their lineup of speakers in the late 2019, and was wondering if it worth waiting for this. I have no information about them, except that will have power subwoofer, no idea how big or efficient will be the smaller ones. 
My budget is $7000 max. 
Thanks in advance
