So how much separation is ideal? And how much can you get by with? Must they be flush with the corners or can you bring them out into the room a bit? I was planning to have a false wall and I would not want the speakers to have any part of the screen blocking the horn. Other placement concerns I should know about? It is kind of a long shot for me but I can't help but want to know more about these speakers.
My room was about 16' wide and because of the (wife mandated) layout of the room, there was a table right smack dab in the sweet spot (Khorns).
Do some layout... 45 degree angles in from the corners puts you where, 7-10 feet back from the front wall? Is that going to work?
I made it work for me but I lived with compromises. I rotated the tops a bit to help but it only did that....helped.
Here's another tidbit for you. (Preface, I had ALK extreme slope crossovers in them)... I stumbled onto the fact that at about 30' of measured distance, the Khorns took on an entirely different (better) quality of sound. I call it "one voice" where the coherency of the speaker was as a single point source. I did not detect this quality in the room.
Long story short, I later learned that it was because of them being 3 way and I also suppose the extreme slope crossovers added a bit of time (therefore distance) for the three horns to melt into a perceived single wave front.
Out with the Khorns, in with the Jubilee's and soon, I was going to this 30' spot to hear how much better they sounded at the same 30' distance.
I was initially let down that they didn't sound any better..... until I put the pieces of the puzzle together.
Being a 2-way speaker, a crossover point was dropped and now, the speakers didn't require the 30' of distance to merge into a single voice. This single voice now happened 7-10 feet away from the speaker.
The net result is, I was now hearing the 'single voice' of the speakers while being IN the room with them whereas, to hear this same higher quality of sound with my ES Khorns, I had to be 30' away from them.
Noticed the same thing when I took my single (also ES crossover) LaScala outside. After about 25 feet, it became a point source of sound.
All that said... I am of course, a fan-boy of the bass horn loaded offerings so take anything I say with a grain of salt.
