Efficient speaker: Zu, Tekton, Volti, Klipsch, Fleetwood?

We’re moving and I’m looking for a high-efficiency, high impedance speaker that can fill a very large “great room” with smooth, open, detailed sound, both for serious listening and casual background music. I currently have Devore Super 9s, but those will be going in a separate dedicated listening room. I thought about getting another pair of Devores (maybe the O/93) for the great room because I love this brand, but I’m interested in other possibilities The new speakers will be on either side of a 6-foot TV console, so they’ll need to sound good fairly close to the wall behind them. And they will need to have a reasonably good WAF. They will be played mainly at low-moderate sound levels and our tastes include rock, classical, world music and “spa” type relaxation stuff.

Anyone who is familiar with any of the following candidates, please feel free to sound off. As you can see, price ranges are all over the place:

Zu Soul Supreme

Tekton Lore

Volti Razz

Klipsch Forte IV

Fleetwood Deville

Others?
