Universal room treatments

I’d like to know if there are room treatments that almost all rooms need for optimum sound. I am moving a not picked out yet system into a dedicated room ( 14 x20 x 7 ft room) with carpeting , concrete floor and no windows. What treatments are essential even before I purchase any speakers etc. In other words, are there basic treatments I should do before any components are purchased? Than you in advance.

I like the whole free wheelin’ idea of equalizing pressure zones in the room using small tiny little bowl acoustic resonators. I sell some what people oft tell me are too strange for them Blue and Green dots for the room walls and ceiling respectively that address an esoteric problem involving the sense of perception of sound and the feeling of being enclosed in small spaces.
