Usher 718 BE
These are very cool and sort of different looking speakers that perform exceptionally well, esp for what they are.
I read a ton of reviews before I bought a used pair and I believe every single review spoke about the bass performance, but at least one of the reviews said that they actually perform "more like a floor stander".
According to the requirements you laid out I believe it may be a good fit.
I can tell you that the beryllium tweeter is very special. I have kind of a large bedroom in my place and have a pair of Martin Logan Summits that I love and if you can believe this, the Ushers actually do strings better than my ML's.
They're definitely cool looking.
