Any chance of info from the Barefoot folks on what the switches and ports on the back are? Sub -2 and +2? Voice - is this like the relaxed voicing pushbutton on the '27s? But it looks like it's a jack. Is the USB port for diagnostic/repair functions only, or does it allow for user adjustability? What's the story with the AES inputs? Wasn't expecting that, though I can understand the appeal. Excited to see/hear these in the near future, even though I can't imagine being able to afford them for quite some time. Loving the description of the '12s as a "P.A. system with ultimate fidelity" though!
