Have not had time to experiment. Too many other things keep getting in the way. Right now it is 100+ degree heat! But talking with John Hannant, they do not seem to be particularly sensitive to location. They have customers using them pointed backwards, using multiple tweeters (up to 3 per speaker!) and some even running them out of phase.
This all sounds super zany until you stop and think about the physiology of human hearing. In the Cliff Notes version we have three different but somewhat overlapping systems. One for very low frequencies is really good only for volume, and not even all that good at that, it hardly registers until the volume gets fairly loud. (Which is why the Loudness switch was invented.) One for midrange is incredibly sensitive, able to localize with high precision, fine tuned to such subtle details we can tell a violin from a viola, distinguish a million different human voices, etc. (Which is why the midrange is so important, why speakers must be positioned precisely, etc.) Yet a third system registers ultrasonics- frequencies too high to register as distinct discrete sounds. We literally cannot hear them. Yet the majority of cells in the ear canal are designed to detect them!
As if all that weren't cool enough, the best part is we have something that combines all the inputs from these disparate systems into one solid and dimensional mental map of our world!
This is why five subs spread around at random are able to produce impeccably precise bass. Why the two main speakers must be positioned with extreme precision. And why super tweeters we can't hear not only work, but improve even very low bass.
