3m is about the shortest listening distance you can hope for, and it will take PRECISE tilt adjustments at that.
This is based on your listening seat height. The closer you are, the less forgiving this adjustment is, due to the spacing between drivers.
Also, I've never found a room that cares whether you have UNOs or DUOs. The requirements are virtually interchangeable.
Since the DUOs are significantly better, I'd go for them if possible, maybe even used, over UNOs (which are good, but there's a reason 8 DUOs sold for every UNO).
