The Jrs are front ported, so the issue of the port being near the wall is not an issue. I think the Jrs will react as any average speaker would to near wall placement (not good) If this is your only option you should look for speakers that will do well with that limitation. Von Schweikert has a lot of ideas for different setup configurations including stuffing the port with dacron fill if the bass is boomy. The bass is a standout feature of the JRs and should not be in least bit boomy.
I think given your limitations and what I know of the JRs they could prove to be a frustration to get sounding Just Right. With enough care and consideration these speakers are capable of some real magic though.
