I'll nominate those Tennessee Sound Company speakers from over 10 years ago that looked like oil drilling rigs (I was only kidding that they looked "cool" in the other thread). And those Unicorn speakers mentioned above really didn't look great in their pictures, either. Finally, I just think the Jadis speakers look like Yosemite Sam, so I nominate them here as well.
Ugliest speaker ever?
I've been following the thread seeking nominations for the "coolest speaker ever", and I can think of a few speakers that merit such a distinction. While we're at it, however, let's list some of the ugliest speakers ever designed. I can think of a few recent ones, such as the Avantgarde horn speakers (Uno, Duo, etc.), and the Calix Technology Phoenix Signature (see page 58 of the May issue of Stereophile for a photo). Other nominees?
