They are. I'm not letting out any secrets. Ian has posted at least once that they will be available for near-field monitor applications which I suppose is for recording studios. They will have the same FOC as the passives but of course with higher accuracy. The listening window and sound power curves wont be like the active LFRs though due to the fact they won't be "omni-directional".
