The house we are currently looking at has a ~11' wide room with two nice corners, so ears could be 6 1/2 - 8' from the front wall (6pi axes crossing in front of ears).
So just to confirm on the corner horns, the mids being at 43" high, and the tweeter at 54" high (well above the normal 35"-40" seated ear height), shouldn't sound like output is coming from above? Or maybe my seating distance too close to consider 6pi's?
I've already thought of creative ways to shorten the 6pi height a few inches (without changing the woofer relationship to the other drivers or the corner, or the width of the box as not to impede the horn effect) so that might be an option.
