Speaker for ambient music in large room with vaulted ceilings?

We have a large room with 16-18ft vaulted ceilings.

left speaker is in an open area which goes to 2 rooms and a downstairs stairwell.

right speaker in a closed off corner! Which is why the right seems to have more bass, and overall better sound.

smallish speakers, energy rc-70’s.

they do a darn good job of filling the large room with, whatever is playing.

metal, rock, blues, 

have good high powered amps and a good source!

never clipped the amps, good audioquest cables.

Seen a energy veritas 2.3 for sale used. Great speakers for a large room!

In case this helps someone later, I wound up trying out several speakers and settling on the Bowers & Wilkins Wedge.  I also tried the Clear Crescent, Marshall Woburn 2, B&W Zeppelin,  and Sonos 5 (in descending order of an preference). 

The Wedge did the best job in distributing the sound in the room, played loud without any distortion, had great and clear highs and mids, and a great form factor.  The Zeppelin was similar without as much dispersion of sound and slightly more difficulty with clarity and loud volume.  The Crescent was better than the Zepplin and almost as good as the Wedge, but lacked some clarity and did best when you were right in front of the speaker.  Similarly the Woburn 2 sounded great, but you had to be right in front.  The Sonos 5 was disappointing in most categories.
