Hope it works.....clicking on the link takes you to a dead video, but the image of the horn on the building is beyond massive. Jeb, you'll appreciate this one.

I wonder what it is?

That thing is located in Toronto. There was an article on it (which i'll try to find) but if i remember its just an art piece.

Here is another "art" horn from Toronto (painted same colour):

That central part is just BEGGING to have a woofer shoved in it.
