Speaker Help Please: Floorstanders around $1Ok to fill very large space with no sub

Hi Gang, haven’t posted in here in years...
A great friend of mine is going through major remodel and looking for 2 large floor standing speakers to fill a great room 38’ long x 20’ wide with a celling that slopes in one direction from 15’-8’. so about 7200 cubic feet. 
He is very serious about music. Used to book bands. He listens to a lot of New Orleans groove-based music and Americana. His wife loves female singers, like Brandi Carlisle.
My main advise to him is, since he/his wife don’t want a sub, they will need speakers with sufficient low end.
Haven’t thought too much about amp yet.

He will also use the system for 2 channel home theater watching.
Thanks for any suggestions
