It is fascinating how people's idea of beautiful differs. The majority of the speakers mentioned in this thread seem to be kind of cool speakers that people want, looks be damned.
Like those incredibly ugly Genelecs. Or the slightly less ugly but still not close to attractive Revels.
My definition is a speaker that someone who hates speakers would actually like to have in their lounge.
And hence I'll bump my own Davone Solos.
My current wife has endured 10 years of me buying, building and swapping speakers. Her very low standard has been less ugly than the previous speaker is good, but invisible would be better.
The least ugly and most invisible was the KEF LS50.
Until I bought the Davones.
Now they are 'her' speakers. As much a piece of art as the Egg Chair next to them. Fortunately they sound very good as I will never be allowed to upgrade.
That is beauty.
And thus I win.
