Although the drivers themselves are round....they are aligned vertically.....so putting a speaker on its side changes it's orientation and dispurtion characteristics.

Also some tweeters are designed with defraction lenses to alter dispurtion characteristics.....turning the lense would change it characteristics.

Also...the shape of the enclosure can also play a big part on its imaging characteristics as well.
