These can be placed very close to the wall behind them, tailor your bass response with that distance, work a little with toe for staging etc., good to go.
Another really fun thing which I tried briefly, and I believe was mentioned in Stereophile(?) review possibly, place a pair, so two pairs back to back, for an even more Omni presentation. It worked quite well. One had to be a bit more careful with positioning, but it worked quite well.
Many fun speakers out there to listen to, sometimes it is just taking the time and effort to search them out and hear for yourself what sounds good to your ears!
