I have extensive foam absorption on my side walls and ceiling with 90oz carpet. My front and rear walls are 3/4" cherry plywood with the entire room super strong and non-resonant (my profile indicates the $150K that went into building it). My old Focuses were not good sounding here. The Signature IIIs with the rear firing tweeter obviated the need for front wall absorption. My Von Schweikert VR9 SE Mk2s have adjustable rear tweeter and sub with such great dispersion that I don’t seem to need anything on front or rear walls. I used to own 5 different stat speakers over two decades. They were about 5 to 6 feet from the front walls mostly in a room 5,800 cu ft room. They did not appear to require rear baffling of any time although I had considered an expensive curved foam design for the Monolith IIIs.
The Clarysis is a fine speaker. In a large enough room with ample depth to the front wall, they may not require any baffling (absorption or dispersion). At under 3 feet, very likely necessary.
