You might want to look at the Vienna Acoustics Schonberg. It's only 3.5 inches deep, is made of brushed aluminum, and was designed for near wall placement. It received a great writeup in HiFi Plus a little while ago. It's starkly modern looking, so you'll probably either love it or hate it. Other beautiful loudspeakers that come to mind are from Opera, Sonus Faber, and Vienna Acoustics (non-aluminum line), but most will probably suffer from near wall placement.
