Back in the Old Days, Like pre-covid, Members here would makes theirs systems available for people to come and listen, if they were in the neighborhood. It will be interesting to see if that practice resumes as levels of infection reduce. So many of the participants here are extremely kind, but I doubt even the most charitable will risk death to give you a show.
That said, you might give a general approximation of your region, which you might be will traverse for a listen, some one might oblige, assuming all take good precautions, with vaccinations and mask?
Open Baffle designs seem to be spreading rapidly, and there is a good chance a dealer in your area might have a spatial system?
I note that you mention the size of your room, which seems to be a great starting point. Just keep in mind the distance from the walls you will need to have an effective system. Danny says MINIMUM of 3 feet from the wall, and more is likely for best set up.
