+1 to a sealed box like ATC, though you’ll still have a considerable amount of boundary reinforcement. Audiovector speakers work very well close to the rear wall, their recommended distance for the R1 is as little as 15cm even with the rear port. I suspect in your room it will give you a really strong bass response with speed and slam. The only caveat is they are not the most engaging speakers at low volumes due to being quite neutral/slightly lean in the lower midrange and presence region which means they are best closer to realistic volume levels (they can play crazy loud without compressing), however the R series seems better than the SR I had in this regard and I believe this will be even more of a problem with Magico. For lower level acoustic listening I suggest comparing the “neutral-ish” speakers like Magico, Audiovector, and ATC to the warmer ones like Spendor, Sonus Faber, Devore, Vandersteen and seeing which style clicks for you. The good thing is in your smaller room there’s less risk of the neutral-ish speakers sounding lean.
