I've seen a lot of silly-looking speakers in my day, but these might be the silliest. They're the Acadian Audio 100-watt Pnoe Speakers, and they are just downright ridiculous.
Why are they shaped like that? Well, according to the marketing materials, it's to "create the smoothest, roundest path for the sound wave front, without any obstructions, so that there are no sources of standing waves and spurious reflections." Ho-kay. The price of these guys isn't public, so you'll need to contact Acadian Audio if you're interested in them. But expect to pay more than is sensible for gigantic, ludicrous horn speakers.
