Do rectangular front horns have to be horizontal

Just wondering why I see so many horizontal front horns when there are line array speakers etc

In other words, why arent there more vertically shaped shaped front horns? I can only think of one, possibly two

Perhaps our hearing gear being better tuned to L-R separation relative to up-Down? So, a CD horn is better serving its audience creating a horizontal field. Does it also minimize lobing issues by controlling the vertical to a tighter spread?

Don´t let your eye outvote what your brain knows, it´s exactly the other way round - physics.
Waves bent by a narrow slot - a rectangular horn mounted horizontally squanders a lot of energy by spreading it up and down instead of where it´s needed. PA people accept that as the lesser evil because it makes the boxes less high and thus easier to shlep around.

Though primarily to keep acoustic centers as close as practical.........

GM - "practical", "affordable" and "lightweight" are a marriage still not seen. Be honest - have you ever met a happy roadie?

Haven't known all that many, maybe a hundred?, but as a group they seemed to enjoy their work/lifestyle far more than the majority of the probably several thousand office workers I've known.

Pit, so a vertically shaped horn is feasable? The reason is very important. To make it female friendly!

If I made a front horn with a mouth of say 180 cm height x 45 cm width would it work in principle
not sure what hz that wd go to but anyways.

Hmmm...could you go back to think about rearloaded? The Sachiko

might be what you need and still be the size you can get away with.
