"I remember reading of this stuff years ago. I looked at your referenced patents and it looks to me that Stinger 4515997 is the real prior art."

When one thinks about it and browses through the old patents, there are no truly innovative ideas in this hobby. One could take that patent you mention and carry it even farther back on to the WWII experiments in digitally encoded communications and further to the end of the 19th century where there were experiments with mechanical digital encoders. I just chose these patents as representative of the idea and to provide material for discussion with the more specific outline of how it might be implemented.

"Seems like the main problem with these schemes is having the sound source location vary as a function of amplitude so the array gets sort of convoluted. I would think that running the signal through active crossovers first would help as the size and mass of the transducers could be matched to the frequencies."

Could you elaborate more on this? How would localization be a function of amplitude> How could active crossovers be implemented into an array where the signal is broken apart according to bit depth (I really need a better way to say that) as opposed to frequency?

"Now that every home seems to have a WLAN that chunk of the infrastructure seems in place. While it presents some design difficulties, it provides far more freedom to produce well performing systems."

Now that's a really interesting thought. This approach could be paired up with some future form of wireless media server to create a completely decentralized music system rather than just one that bypasses the need for analog components.

"And that's what we hear, the system, not the components."

Ideally, we'd hear neither and instead just the music. Such is my goal at least, to have gear with the least sonic signature imparted onto the music and my experience with digital based components possess strong potential for that.

Then again, there's also the strong possibility that I'm just currently enamored with the novelty of this approach and am overlooking the limitations in much the same way others resistant to change overlook the potential.
