Devore O/96 vs Stenheim Alumine 2

Looking for some high efficient speakers for my secondary listening room / Den.   15' wide by 11' deep by 9'5" tall.  I've always wanted the Devore O/96 speakers but worried that I would have to keep them very close to the front, 6", wall and they are ported on the back.  Probably too big of speakers for the room and should look at the O/93 or baby.  Plug the ports on the O/96?

But we will probably move into a larger home where I would have more space.  

A good friend recommended Stenheim Alumine 2, efficient speakers and ported in the front.  Worried they might be too small if/when we move into a larger home.

Want this room to be a warm sounding room, lots of texture, jazz and female vocalist, low volume levels, vinyl, possibly tubes but maybe low power class A.

Thoughts?
