positioning of a horn speaker


I have a pair of Tyler Acoustics PD 15 speakers that I am having trouble positioning. They have a 15 inch woofer and a flare type horn.I am having trouble with their imaging poor center fill with the image coming from both
R&L speakers. Are there any suggestions on positioning? I have never had a
pair of horn speakers.

The shape of the horn figures heavily in this matter. Mine are only 40 degrees dispersion pattern. This is pretty narrow but necessary in this design so that the horn unloads at the proper rate. Mine, therefore behave better with toe-in and I am better off being back some twelve feet or more. If your horn has a much wider dispersion, you might wish to spread them further.
If, as I suspect, you are dealing with an off-the-shelf horn, there may not be any right way to perfect it and you'll have to just experiment until you get something you can live with.

Vertical dispersion is very narrow in tractrix designs and limitation in that area may be contributing to your problem.
