How do you properly set up a horn speaker

Some horns can be placed closer to room boundery then conventional but otherswise its like the setup for most loudspeakers consider radation patern and toe in if needed.

3 of my in home front loaded horn systems are all near rear wall and or corner.  Its one of the benifits of horn ownership. But you wont listen and will just drek it all up by placing like a crazy audiophile and later sell and try something else hey its what most are doing so have at it.

Horns can work wonderful in nearfield keep in mind most older music was master using horns many times in nearfield only horns that require distance are those not properly time aligned. I use a massive pair of community leviathans in my office nearfield system its far better than any of the crazy costly modern sota dynamics I have used in same. Klipsch horns are not time aligned and need more space or they sound forward a good reason for Klipsch owners to get out and hear other horn designs.
