Room Acoustics

I’m moving into and new place and going to have a dedicated listening room for the first time. No more living room listening for this guy! Though my room is going to be a little acoustically challenged and I was hoping to get some advice on the best ways to midigate the problem. The room is 13’ x 12.5’ x 6.5’, I know, super low ceiling :( Floors are concrete and I was planning and throwing an area rug down. Other then putting up some acoustical paneling does anyone have suggestions or clever ideas that would help? Thanks!

my system:
Rega RP6 turntable
Ayre P5-xe Phono preamp
Ayre Ax-7xe integrated amp
Vandersteen 2ce speakers
I listen exclusively to vinyl and have pretty wide music tastes. A lot of 60s and 70s rock and modern indie rock, as well as a little electronic and a little jazz.
