I have 2 AIR12's tops and 2 AIR15s subs. I watched the video where one of the reps or bosses was demoing the AIR15s and in the DSP there was CLEARLY an option that you can select the top (air10, air12 or air15) but I can not seem to find it and I don't see it in the manual? Am I missing it? Did they change it before it was released but not change the demo vid? I just wanna make sure I am using it to its top capabilities and that was a real selling point to me and now I cant utilize it? Please let me know.
