I recently retired a pair of giant Klipschorn corner horn speakers that had to be placed in corners so that the walls would provide the remainder of the 20-foot horn. I was used to a wide-looking speaker with a wide mid-range horn. These tall tower speakers seemed weird at first because they were narrow. I had the illusion that there were two separate stages for the music. But when I closed my eyes, this feeling went away and I felt a broad sound stage. If you must have a visual clue, go ahead and mount them horizontally at ear level for a psychological visual effect of a wide sound stage. No cabinet because you need to keep the ported bass open. Put the rear ported base inward. But really, just get over it. Ignore the look of the speakers and just listen. You'll be pleased.
