I had the original Acoustat X speakers, which I bought new. Sold due to downsizing and still regret it. The only thing I didn't like was the one person only beaming imaging.
The Acoustat panels are close to indestructible.
You could try a few things.
In terms of box speakers sounding boxless, IME Wilson Benesh produces speakers with great imaging and incredibly low cabinet noise. I saw an older pair of Discovery stand mounts on e-bay today (no relationship).
Upgrade your subs to new active subs, look for some Sound Lab speakers, or maybe Eminent Tech speakers (link below) Good luck with your search.
